Glitches

A glitch, otherwise known as a "bug" or "fault", is an error in the game that produces an effect that was unintended by programmers. They can be exploited to gain advantages over other players and may be caused by severe lag. Using glitches to get an advantage in online multiplayer is often considered ''cheating. ''Glitches can also be unintentional and cause minor/severe problems for the player. It should also be noted that Glitches and Hacks are different things, the latter requiring the intentional modification and abuse, whilst Glitches are unintentional but can also still be abused.

Below are glitches that can be found in Call of Duty games. Minor glitches are not included.

NOTE: All patched glitches can be preformed if the player uses a patch blocker or signs out and deletes the patch. or does the glitch in split screen (confirmed in Modern Warfare 3 only)

M12 Firing Glitch
On the final level that takes place in Aachen, the player would start by fighting their way out of a hotel-like building. Once in the main stairwell, some Panzerschreck teams will spawn, shooting at the allied M12. Kill them, and take their Panzerschrecks. If a rocket is shot into the multi-storied building at the end of the road in which the M12 was going to destroy, it should do it's crumble animation as if the M12 destroyed it.

The player would then proceed out of the building, and continue through the level. Once out of the building, the M12 will get ready to destroy the building which has now been destroyed by the player. When its cannon is fired, the screen will go black with white text saying something along the lines of "An unexpected error has occurred. Please refer to the GameCube instruction booklet for more details." After that, nothing can be done, and the system must be shut off or rebooted to continue game play.

The Invincible Soldier Glitch
In the level An Easy Detail there is a section where the player has to kill some enemies hiding in building, just after running out of the woods. The player is supposed to go around the front, however if the player goes around the back, there is a window the player can see an enemy through. If the player tries to attack the soldier in any way with any weapon, he will not notice the player or take any damage. However, when the player sees the soldier again after entering the building he can now be killed.

Flaming House Glitch
On the Eilendorph Ridge level, in the beginning before the firefight in the cemetery, there is a two story house that is on fire. On the ground floor, there are multiple windows. The player can jump into one of them, granting access to the inside of the building.

M1919 Reload Glitch and Carcano M38 Glitch
On the level Operation Husky, if the player has to reload but is using the bipod, the game will play the reloading sound, but not the actual action. After the sound plays, the weapon will play its animation correctly. This is because the game tries to play the reloading animation and the movement animation at the same time. Also in the level, there will be a pick up sign for the Carcano M38. When the player picks it up, there will be nothing in the player's hands.

Snake Glitch
The "Snake Glitch" is a means for players on the PS2 multiplayer to gain an unfair advantage by appearing to other players as being in the Prone position, but moving as fast as if they were running. This gives the player a much lower profile, making them more difficult to attack.

The glitch is activated by jumping, holding the circle button to go prone while in the air, and repeating three times. On the third time, the player presses X to get up while simultaneously pushing the left analog stick forward to run, and L3 to sprint. To the player activating the glitch it appears that he is standing and moving normally; to others, he is in the Prone position, sliding along the ground at a running speed, and very difficult (but not impossible) to attack.

The glitch can be activated in any map and any multiplayer game type, but only works on the PlayStation 2 version of the game.

CTF Physics Glitch
In the PS2 Multiplayer, sometimes if a player were to melee with the enemy flag in hand, they would fly at a high velocity into the air and travel far across maps, usually landing unharmed. The event can prove very annoying as the flag bearer can score a point very easily depending on where he was flown off to, enemies trying to kill said player may lose their opportunity to do so. However, this is rather uncommon as there must be certain circumstances for players to do so, an example would be trying to melee a player at a reasonable distance and lunging at them. This glitch is most noticeable and more frequent in open Multiplayer maps such as Eder Dam.

This glitch is unconfirmed on other versions of the game (Xbox, PC).

Last Stand Glitch
The Last Stand Glitch is known to happen to some players while they are killed when switching their pistol for another weapon. In order for the glitch to occur, the player must be switching his side arm for a primary weapon. If he is killed by body shots and has the Last Stand perk activated, the player will go into Last Stand mode with the recently acquired primary weapon.

Last Stand Grenade Glitch
This glitch will occur if the player is holding a Stun Grenade or Flashbang when they are hit by bullets and knocked into Last Stand. The stun/flash grenade they were holding will turn into a frag grenade with zero seconds on the timer and explode instantly, killing anyone near the player.

M2 Glitch
This glitch is on the single-player level Charlie Don't Surf. In the section of the level just before entering the TV Station parking lot there is a demolished building. Inside the wreckage, find an overturned mattress. By jumping, the player must go up the low wall next to it until they are on the top of the outer wall. Walk along it to the left and then turn right and jump for a low roof. Then, jump off on the other side and the player will be in a previously inaccessible part of the map, the same area the player can see from the roof of the station just before they find out Al-Asad's broadcast is a looping tape in the mission. From here, the player should walk up the hill near the station and continue until they see the concrete river bed. Walk along the concrete river bed until a white pipe is seen. Walk across the white pipe and jump through the fence on the other side. Once on the other side, go right and walk past the two buildings to the left. Around the corner, there will be an M2 Browning Machine Gun mounted on nothing, which can be used by the player. Players on PC can simply use the "noclip" consol;e command to get to the M2.

Airborne Glitch
This glitch allows the player to complete the challenge called "Airborne". To begin the glitch, start a match on Crash and go north to where a tall building with 3 stories is. There, the player needs to exit the building from the second floor side, where the ladder to the third floor is. Once outside, the player should see a blue barrel next to some stairs. Run towards the barrel, jump, and then go prone directly in front of the barrel. Then, the player's character will start to look up by itself. Once its sight goes all the way up (the character's gun should be pointing almost at the sky), press the button to jump twice. The player will be stuck "falling". All the player needs to do now is shoot two enemies, which will complete the "Airborne" challenge.

Pipeline Glitch
In the underground area of Pipeline there is an indented area of the wall with a fence covering it and blue pipes running along behind the fence. If the player jumps unto the ledge in front of the fence and faces the wall then goes prone, the player can move sideways and bypass the gate going "inside" of the pipes.

Game Over Glitch
On the last level of Call of Duty: Modern Warfare: Reflex Edition, in the last segment when the player has to successfully get off the collapsing bridge without falling to their death, a glitch is present. The player must immediately jump backwards when able to move out of his/her damaged vehicle. This action will make the player fall off the bridge. On the way down, the game may save a checkpoint while still falling. The first time the player falls, they will die. However, when the player respawns at their airborne checkpoint, they will survive the fall and land on the riverbed below. There, the player may wander along, and is able to exit the map through multiple terrain holes. The helicopter that is scripted to fire at the player will still carry out its command, so be careful because as they player can be killed by it.

3 Weapons Glitch
There is another rare glitch on the level "Game Over", found just after when the bridge is hit by the Hind and the screen goes black. If the player is not holding the RPG-7, the game will say "Press and hold X to swap for RPG-7. However, for a brief second this will change to "Press and hold X to pick up RPG-7. This does not happen every time. When it does, the player will be able to pick up the RPG without swapping it for another gun, allowing the player to carry three weapons. If the player is holding the RPG, they may continue the game with it. However, it requires multiple tries and jumping right when the player gets the chance to crawl out the vehicle. It is hard because the player is at the edge of the bridge and is subject to falling off.

Skip Enemy Glitch
At certain levels, such as "Charlie Don't Surf", if the player advances through the level quickly, overlapping NPC speeches, the enemies that are scripted to spawn and attack do not appear. This allows the player to go through certain portions of the level easily. However, if the player backtracks to the area where the enemies are supposed to spawn, they will appear. Moreover, some levels require the player to eliminate certain enemy personnel to advance, such as the machine gunners in "War Pig". They will not appear, and the player will not go through the door Vasquez is supposed to open.

Crossfire Glitch
This glitch consists on walking in the sky in Crossfire. To do this, the player must go to the building in the bottom, where the OpFor team starts, climb into the 2nd floor by jumping over furniture. When the player makes it up, they will be able to walk around. (Confirmed on PS3, only able for offline)

Shock and Awe Glitch
During the mission Shock and Awe there is a glitch to where the missile will miss Pelayo's helicopter. What would happen is Peyalo's helicopter hovering where it will crash land, while the player will fly around the area and eventually away from the city.

Unlimited Ammunition
The unlimited ammunition glitch is a glitch that makes the amount of ammunition there is disappear, allowing unlimited ammo. To do this, players would set up a machine gun that has a bi-pod attached to it, then press up on the left analog stick (PS3). This has since then been patched.

Bayonet Jump
To perform this glitch, have a player on the opposing team stand a few feet on the other side of a slanted object. Touch the object and try to bayonet the enemy player. Doing so will launch the player into the air. The glitch was patched for PS3/360/PC, yet a few glitch spots remain.

Teamkilling without being kicked
If the player held a Bouncing Betty out and killed teammates with the knife melee attack, they would not count towards the three teamkills necessary to get kicked from the game. This glitch was patched in April, 2009. Video:

Three Gun Glitch (Nazi Zombies)
Zombie Verruckt: To do this glitch, the player must have the power on, enough points, Bouncing Betties, and maybe one last zombie to keep the round going and to save the player time. The player can put the first Betty wherever they want. Then go to the desired Perk-A-Cola machine. Hold down the button that places the Betty and do not let go. Once the player drops the Betty, press the action button to buy the cola. If done correctly, the player's character will not have any gun, so they are able to buy one off the wall or get one from the Mystery Box. Once the player has purchased a weapon, they can keep on switching guns and will notice that they have their new weapon as well as their old ones for three weapons total. The player can keep performing this glitch for more than three weapons. This means that if the player has all the perks, they will have to go down and get revived again to do the glitch another 4 times.

Shi No Numa: To do this glitch, the player will need enough points, the Mystery Box close to a Perk-A-Cola machine, and maybe one last zombie to save the player time. This glitch is much easier than the one on Verruckt. First, activate the Box. Then go and buy the perk. While the player's character is still drinking the bottle, quickly pick up the weapon from the Mystery Box. After the weapon has been picked up, they player will now have three weapons. Sometimes after the player receives their third gun, all of their weapons get full ammo for some reason.

Der Riese: There are several methods, however most require at least 2 players to perform. One only method requires one player, however. To do this, the player needs the power on, the 3 teleporters linked, Bouncing Betties, and at least 5200 points. First, leave a crawler, since this glitch takes some time. The player must put one of their guns in the Pack-A-Punch machine. Then while it is upgrading, run and buy the Kar98k (hence the extra 200 points). Then run back to the Pack-A-Punch machine and take out the Bouncing Betties by pressing right on the D-Pad. The moment the Bettie comes up, take the gun from the Pack-A-Punch machine. This will allow the player to keep all 3 guns. However, this cannot be used to get more than three guns. If two weapons are already Pack-a-Punched, the glitch will cease to work if the player Pack-a-Punches the third gun.

Note that once the player has every weapon that is obtainable, the Mystery Box will only hand out the Colt M1911.

'''Be sure to keep the last crawler or zombie occupied so that it does not attack any of the players. Have at least one person the zombie can follow. Switch players when everyone is ready so that everyone has a chance at getting what they want.'''

No Weapon Glitch (Nazi Zombies)
In Der Riese, if the player buys a Bowie Knife and gets downed, they will appear to have no weapon when they are revived. However, they can get their weapons back by pressing the weapon switch button.

"All stances not allowed"
Occasionally, in Nazi Zombies, when all players die and they lose connection with the host, a message will pop-up saying: "ERROR: All stances, including crouching and standing are not allowed in online matches", but this is a harmless glitch and will not cause serious trouble.

Running After End of Match
Status: CONFIRMED

Details: This glitch allows the player to run around after the end of a match when the screen grays and "VICTORY" or "DEFEAT" and the score is displayed. To do this, the player must have a predator missile. If the match is about to end, and the countdown timer is at around 5 seconds left, the player must fire the predator missile. The predator missile must detonate after the match has ended and the player is about to be forced to close the laptop. If done correctly, the player will close the laptop like normal, but be able to move freely until the camera changes from 1st person to 3rd person and shows player scores. If the glitched player runs in front of another player, they can be seen moving after the match by another player.

Hidden Sentry Gun
Status: CONFIRMED/ACTIVE

Details: This glitch allows for sentry guns to be "hidden." Two sentry guns will be necessary to do this. Place the first sentry gun wherever it is desired. Place the second sentry gun directly on top of the first and move back slightly. It should look like one sentry gun with two swiveling heads. The first one will be destroyed first as it is in front of the second and will take the damage. Once destroyed, a destroyed sentry gun will appear over top the sentry gun that is not yet destroyed. This destroyed sentry gun will cover the second making it impossible to enemies to see the active sentry gun, only the destroyed sentry gun. It's also possible to hide a sentry INSIDE the support beams holding the destroyed highway in Underpass, however, this has been patched.

Screen Glitch
Status: CONFIRMED

Details: Hold down the "equipment" button (with Throwing Knife equipped) after shooting with any weapon will tilt the screen slightly to the right. If done correctly, the gun will have no sound at all during killcams. It has no beneficial effect on the player at all.

Counter: Not needed.

Whiskey Hotel Glitch
Status: CONFIRMED / ACTIVE (February/13/10)

Details: In the campaign mission Whiskey Hotel when they player gets past the oval office, they will have a small firefight with enemies before they get to the president's press room. When the player sees an enemy in front of a window, they player must kill him and go prone. The player must then shoot the two lower windows and they can crawl through and attack the enemies from the side. The player can then go around in front of the White House.

Whiskey Hotel Freeze Glitch
'''Status: Depends on game copy. Confirmed on Xbox 360 Hardened Edition.'''

Details: In the campaign mission Whiskey Hotel, after the player crosses the lawn, past the MGs and spotlights on the west wing roof, walk into the hallway before the oval office. The game will then likely freeze up (even the guide button) and forces the player to turn the system off manually. This is more common on the Hardened edition of the game.

Counter: Run past the hallway before the oval office, or swap discs.

Shooting Equipment
Status: CONFIRMED / ACTIVE

Details: While in multiplayer, a player must use One Man Army Pro, and a Tactical Insertion. The player must have their One Man Army class selection menu open, ready to select another class. At the same time, the player must select their class and press their equipment button to deploy their tactical insertion. If done correctly, the player will run around looking like they are about to use their equipment (holding a claymore, throwing a fragmentation grenade, etc.) This works with all equipment except for the Blast Shield. For Tactical Insertions, the player will be holding a broken model of the flare. Every time the player shoots, they will run the cap over the fuse, like they are planting the flare repeatedly. For claymores, the player will hold the claymore out like they are going to plant it. When the player shoots, it appears as if they are planting the claymore repeatedly. For C4, the player holds the detonator, and every time the player shoots, they appear to throw the C4 repeatedly. For Semtex, Throwing Knife, and Frag Grenade, the player looks like they are repeatedly throwing the equipment. This does not affect accuracy, damage, or anything with the gun. If the player falls from high up, sprints, throws their equipment or special grenade, or runs out of ammo for their gun, the glitch will end, giving the player their gun back.

Minigun Sniper Glitch
Status: CONFIRMED / PATCHED

Details: While in multiplayer, anybody wielding a sniper rifle can click the Left Stick/L3/Shift to hold his breath while aiming down the sights on a mounted minigun. It does not affect the minigun's performance at all. Furthermore, while using a sniper rifle and aiming down the sights on a minigun, the Minimap radar disappears, as though the player is using the scope of the sniper rifle.

Minigun Riot Shield Glitch
Status: CONFIRMED / PATCHED

Details: First, use One Man Army to change to a riot shield class. While changing, use the minigun. When the player finishes changing classes, there will be a Riot Shield in front of them. There is also a way to perform this glitch without One Man Army. In the beginning of the match, there is a bit of time to switch classes even after the game has started. If the player is close enough to a minigun, they can use the minigun, pause, go to change classes and pick one with a riot shield. This will have the same effect of doing it with One Man Army.

Care Package Marker Super-Sprint
Status: CONFIRMED / PATCHED for all platforms.

Details: In multiplayer, a player is able to sprint extremely fast if they equip (but don't deploy) the smoke marker for a care package drop. While just holding the smoke signal they are still able to use their melee knife, meaning the player can swiftly sprint around getting melee kills. Most using this glitch will also use Marathon and Lightweight to make them even faster. This may be intentional; the smoke canister is very light and may have a very high mobility score, perhaps so the player can run to a remote location to summon the drop. This glitch has been fixed by the patch 1.0177, along with the Infinite Care Package glitch. Players will now run at a normal speed when they are holding the smoke markers.

thumb|300px|right|A Video demonstrating the Javelin Glitch

Multiplayer Launcher Glitch (better known as "Javelin Glitch")
Status: CONFIRMED / PATCHED for all platforms.

Details: In multiplayer, a player can use a certain button combination to have a launcher explode if they die, making for an excellent "kamikaze" strategy. To do this, the player must first change to their launcher, then hold their equipment button down so they take out their equipment. Next, while still holding the equipment button, the player must switch back to their launcher and release the equipment button when they feel a light ping. As long as the player has their launcher out, they will explode when they are killed. The most common and preferred launcher and equipment to perform this glitch with was the Javelin and Semtex before it was patched. This issue has been patched.

Multiplayer Elevation Glitch
Status: CONFIRMED / PATCHED (PS3/360) Possibly for PC

Details: In most multiplayer maps there is a certain spot that possesses the right properties to elevate the player. After completing the special technique, the player will be elevated, this will allow the player to exit some maps and roam outside of the normal playing boundaries. In most situations, if the player must fall outside the map, it will kill the player if they don't have the Commando Pro perk.

Counter: These glitches are often difficult to activate, so be mindful of players who are constantly crouching and standing in certain areas. After killing them a few times, they will often give it up.

Multiplayer Ranked Private Match Glitch (Xbox 360 Only)
Status: CONFIRMED / PATCHED

Details: It is possible to glitch the servers to allow a ranked private match of any gametype on any map with up to 18 players. These matches are accessible through matchmaking, do give experience, and count toward the player's overall score. This glitch has been patched, and players trying to perform the glitch will now just receive a message saying "Unable to join game session".

Hidden Glitch
Status: CONFIRMED / ACTIVE (on Xbox 360 and PlayStation 3)

Details: In the Spec Ops level "Hidden" there are 3 different ways to get out of the level. 2 of the 3 ways are in the starting area. One of the ways consists of jumping on cars and eventually jumping out of the map. The other consists on jumping on containers and eventually jumping out of the map. The 3rd way to get out is near the middle of the mission. The player has to get on the roof of the church which is done by glitching through the wall. After that the player simply jumps past the bushes and are out of the level. This glitch is also possible on Call of Duty 4: Modern Warfare because the church in the Hidden mission is the same, it is even at the same angle. Once out of the glitch the player will be in areas from "All Ghillied Up" in Call of Duty 4: Modern Warfare. All of the elements of the level are there, including bottles, and TVs which can be turned on and off by pressing the "action" button. Even the building where Price and MacMillan attempt to assassinate Imran Zakhaev is there.

Last Stand Glitch
Status: CONFIRMED / ACTIVE (28 JAN 2010)

Details: If a player uses up the ammo on an attachment for their primary weapon (such as a grenade launcher), then the player will be able to use their main weapon in Last Stand, similar to the Final Stand deathstreak. This can also be done with One Man Army. If a player is put into Last Stand while they are switching classes, then the player will be able to use the primary weapon of the class that they switched to.

Counter: The user may not be intentionally doing this, but the best way to deal with it is to assess their lethality in last stand. Flanking works well, as does tossing a flashbang or Stun grenade after the player has found cover. Another possibility is to just let them bleed out—often players will kill themselves if they see no chance to gain further kills from their last stand.

Unlimited Care Package, Sentry Gun, and Emergency Airdrop Glitch
Status: CONFIRMED / PATCHED

Details: The player must first get any of the care package Killstreaks. Then, the player must approach a surface that says "Press A (X on PS3; F on PC) to jump," and pull out the care package marker. Press A(X/F) to begin climbing over the obstacle, tap "right" on the d-pad twice before finishing climbing. If done correctly, the player should still have the care package marker in their hands. The player must then throw the marker, pick up the package, and call in the obtained reward (ammo does not work). Then, the player will have another package waiting to be called in. The player must perform the glitch each time they throw the marker. Otherwise, the glitch will stop working. This can be repeated continuously throughout the game, even if the player dies. The glitch can be seen here. There is also an easier way to perform the care package glitch. Have two of any air drops, call in one crate, and wait for it to drop. Switch to any weapon, then hold square to capture the care package, but make sure to hold right on the D-pad at the same time. The player will capture the care package and they will still have a care package marker in their hand. To repeat, throw the marker and use the killstreak. The glitch will stop if an ammo resupply is obtained, or if the player dies.

Unresponsive Multiplayer Glitch
Status: CONFIRMED / PATCHED sometime in December 2009 (PlayStation 3)

Details: When playing multiplayer, the game will randomly become unresponsive and will return the player to the "join match" screen. The coming of this glitch could be indicated by a loss of sound, but this did not always happen. There is nothing that can be done from here. The player's name will be yellow and the name's dark background will not be present. The only way out is to quit the game. NOTE - the system is not completely frozen. Quitting the game will cause in error in the PS3 system where it will restart improperly, the system will not completely shut off and it will beep 2 times. This however may cause freezing but when the game is restarted it should play as normal.

"Out of Memory"
Status: CONFIRMED (PS3)

Details: While not specifically a glitch, sometimes when a game is about to be launched the game will fail to launch and an error message will show. The error message is "Out of memory." This can lead to panic in players but it is a harmless glitch and it is to due to an overloaded server.

Counter: There is nothing one can do to anticipate or prevent this error. Perhaps due to being the host in many multiplayer games online.

Three Weapons Glitch (Second Sun)
Status: CONFIRMED/ACTIVE (March 7/2010)

Details: In the Single-Player mission "Second Sun", after the player gets out of the crashed helicopter, the player must not follow Cpl. Dunn, but rather go to the other side, where the enemies were. If lucky enough, it is possible to get a weapon from the enemies without being crushed by a falling helicopter. When the player goes into the small house where the squad finds cover, they will automatically gain an M4A1 and an M9 while still keeping the weapon they picked up, for a total of three weapons.

Counter: N/A

Assault Rifle Camouflage Glitch
Status - CONFIRMED

Details: First, the player must make two classes with the same assault rifle: one class with a grenade launcher and a sight and a camouflage, and the other with a grenade launcher and a different sight and different camouflage. A glitch can occur which will make the camouflage switch on one of the weapons, if the grenade launcher is selected. After creating the two classes, start a private match. The player must spawn using the first class, and then they must select the other class to switch to when they respawn. The player must kill himself somehow, and after they respawn with the other class, the player must pick up the other assault rifle, swapping it for their secondary. The player must then switch to the grenade launcher from one of the weapons, then fire a grenade and switch to the other weapon. Then switch to the grenade launcher of the second weapon. The camouflage will change to that of the first weapon when the grenade launcher is selected. A video of this glitch can be seen here.

Counter - There is no need to counter this glitch, as it is not advantageous in any way to anybody.

Pave Low Killstreak Count Glitch
Status - CONFIRMED/PATCHED

Details: If the player legitimately earns and calls in a Pave Low, then the kills the Pave Low earns do not count on the player's kill streak count, unless the player earns a kill before their Pave Low does. There is also a glitch where the player receives a Pave Low from a Care Package, and the kills from the Pave Low will count in the kill streak count.

Double Stealth Bomber Glitch
Status - CONFIRMED

Details: It is possible to call in two stealth bombers at the same time, using only one killstreak. To do so the player must be using Precision Airstrike, Harrier Airstrike, and Stealth Bomber as their killstreak setup. They must then earn both the Harrier, and Precision airstrikes. Then they must quickly use both bombing runs, and earn two more kills for the Stealth Bomber (an easy feat, as two bombing runs can cover most of any map) or one if the player has an 8 kill streak. Then the player must quickly launch their stealth bomber. If all goes well two should appear, one after another. The initial Stealth Bomber uses the bombing run used as the 9 killstreak. The second Stealth Bomber uses the bombing run of the Precision Airstrike.

Counter: There is no counter other than killing the user before he can start using his killstreaks, or to call in an EMP. Either way, the likelihood of this is small.

Video Link:

Cold Blooded Pro Glitch
Status - CONFIRMED

Details: When the player has Cold-Blooded equipped, he or she can achieve the pro version of this perk very fast. When a Pave Low or a Chopper Gunner is called in, typically, the player would shoot at it with his Stinger or thumb|300px|right|A video showing the Cold-Blooded Pro GlitchAT-4, making the deployed vehicle waste its flares or even to weaken it. The player would then start firing at the vehicle with a high fire-rate weapon such as the L86 LSW, RPD or M240 to finish it off. However, after the Pave Low/Chopper Gunner is destroyed, it's physical model is still visible, unlike the Attack Chopper and the Harrier which explode immediately after being destroyed. The destroyed vehicle is seen spinning out of control and crashing somewhere behind the map. If the player opens fire on the crashing vehicle, every hit registered will count as '+1' for the total amount of "Killstreak rewards destroyed" in the Cold-Blooded challenges tab.

Counter:N/A

Primary Weapon in Last Stand Glitch
Status - CONFIRMED

Details: If the player has a class with the Last Stand perk equipped, and is positioning a Sentry Gun, firing a rocket, or swapping weapons when put into Last Stand, instead of pulling out a pistol, the player will either take out their primary or the weapon being swapped to (this can be one of the weapon attachments).

Counter: Kill the player in Last Stand. There really is no counter to this glitch.

Stuck in One Man Army Glitch
Status - CONFIRMED

Details: If the player has just brought up the class selection screen with their One Man Army bag and a host migration occurs during the selection, the player will be stuck with their One Man Army bag as their weapon, and they will be unable to switch weapons. The player can only use their knife to attack enemies with.

Counter: Just be killed by an enemy player or leave game. Both will return the player back to normal. An easier thing to do is to go to the start menu and select "choose class". The player then needs to select whatever class they were using when the glitch occurred, they will be back to normal.

No Weapon Glitch
Status - CONFIRMED

Detail: If the player goes to the weapon selection screen right as they die, it is possible that they will respawn with nothing on the screen. When the player fires, it will look like they are switching weapons repeatedly.

Counter: Either die or leave the game.

Attachment Glitch
Status: CONFIRMEDthumb|300px|right|ACR with all attachments

Details: Rarely in the campaign, when the player is killed and then respawns, they will be given the same weapon that they were previously using, but with every attachment available for that weapon, allowing for Assault rifles to have multiple sights, and multiple under-barrel weapons.

No Russian AI Glitch
Status: CONFIRMED PS3

Details: If the player kills the FSB in the level No Russian before they enter the elevator, the script can not have Makarov kill them with a grenade, and will freeze all AI, which will cause them to stop shooting unless the player fires at one of them. In addition, the AI will call the player a coward, traitor, and betrayer, and will break the freeze in order to kill the player. Source

Spawn Reload Glitch
Status: CONFIRMED

Details: Often, if the player is killed during the middle of reloading, the player will respawn with the reload animation still playing. However, this will not affect the ammo counter. This will happen more often if the player's killer uses the same gun the player currently uses.

Fuel Rock Breach Glitch

Status: CONFIRMED / PATCHED

Details: on fuel, its possible to get inside of a rock via wallbreach Source

ADS Animation Glitch
Status - CONFIRMED

Platform - Nintendo DS only

Detail: The player must enter the training room and there will be a cinder block wall behind the instructor who talks to the player when they enter. Go in the door in the cinder block wall that leads to the course instructor and just stand in the doorway. Next just enter ADS mode and the ADS animation will freeze in the middle. As soon as the player sprints, the ADS mode will return to normal. This glitch works with all guns except the M40A3 and the crossbow.

Counter: N/A

Clan Tag Color Glitch
Status: CONFIRMED/PATCHED

Details: Similar to the ability of keeping custom slots after prestiging however the user must select the clan tag option on their playercard, in which they will now have the ability to select the color of their clan tag. This will then be enabled during online play instead of achieving the required prestige 13.

Grim Reaper Glitch
Status: CONFIRMED/PATCHED (Replaced by RPG-7, now is a Grim Reaper)

Details: Sometimes, when killed while reloading the Grim Reaper, the player will spawn with their Grim Reaper constantly doing the reload animation. The player will also be able to zoom in while their Grim Reaper does this, but the accuracy of the player's shots will be lowered because the reload animation blocks the sights when zooming in. The reload animation is reset and is done again once the player starts to run, but when it is finished, the player will have no weapon. This can only be seen when playing any Wager Game mode, such as Gun Game or Sharpshooter. However, this glitch has been fixed within two months of its discovery and the Grim Reaper does not glitch anymore; this also means the RPG-7 was replaced.

Table Glitch
Status: CONFIRMED/PATCHED (Unpatched on PC)

Details: If a player spawns on Five, they can go the window beside the door closest to the MPL in the next room without opening that door. Smash the bottom of the window and repair carefully. The player must repair until the two lower planks have been repaired. The player would then jump on the two planks from the sides sticking out from the end farther from the MPL door. They would then jump to the top of the door-frame and onto the closest table. The player must then jump onto the next table as the previous table is still vulnerable. The player is followed by zombies around the table and can still get power-ups, but if the player stays too close to the edge, they can be downed. To other players, the glitcher appears to be standing on an invisible surface a few feet above the table. The player is left only with their weapons from the start so Max Ammo is always needed. The Pentagon Thief cannot get the player and is an easy way to get the achievement/trophy "Hands Off the Merchandise". The glitch has been patched by the inability to let the player onto the second plank.

Prestiging in Combat Training
Status: CONFIRMED (Xbox 360)/PATCHED

Details: This glitch enables the player to prestige after reaching maximum level, and more than once. The player must be level 50 and will have to start an Xbox LIVE Party, if not in one already. Once done, the player will have to go the their own Playercard. This Playercard menu will have Prestige Mode available, unlike the Playercard Menu straight from the Combat Training menu. If the player prestiges, they will be able to use their unlocked custom classes, but cannot customize them from the Create-a-Class 2.0 menu. A downside to this is, some other parts of Combat Training might glitch. For example, the player will complete the challenges for a pro perk, but will not be able to buy it.

Gold Gun Glitch
Status: CONFIRMED/PATCHED

Details: This glitch enables anyone at any level to use any gun or camouflage, similar to split screen play. The player would join a Team Deathmatch lobby in a party, then back out right before the match began. Then, they would tap B twice, then choose System Link mode. The player would then go to Create-a-Class and select their primary weapon, then hover over Gold Camouflage until an error message popped up. Then, the player would switch lobbies to private match, then customize their class to their liking.

3 Weapons Glitch in Zombies
Status: CONFIRMED/PATCHED (Xbox 360)

Details: This glitch allows users to gain a third weapon, just like the now patched Betties glitch in the game in the World at War maps included with the Hardened/Prestige edition, in order for the glitch to work, a player must down himself/herself along with a fellow player by cooking a grenade in their hand until detonation. The user attempting the glitch must hold the 'action button' while being within normal reviving distance, the glitching player must then be revived and when fully revived will come up reviving the 2nd player instantly. After reviving the fellow player he/she will have no gun, allowing them to buy a third gun off the wall or from the mystery box. This glitch was patched almost instantly on discovery in the recent update.

Crossbow Camouflage Easter Egg
Status: CONFIRMED

Details: Allows the player to use any camouflage on the crossbow, and is simple to perform. First, the user must make a class with an assault rifle, the desired camouflage, and a Flamethrower attachment. Then, the user starts the match. Upon starting the match, the user must switch to their secondary weapon, then press left on the D-pad to activate the flamethrower. Then, the player must kill him/herself or get killed, but before respawning, they must switch to a different class. Then the player should go to the area where they were killed, and pick up the crossbow. It will now have the intended camouflage.

Video Walkthrough

Zombie Walk Glitch
Status: CONFIRMED

Details: In order to perform this glitch, the player must have Valkyrie Rockets and any equipment. The player must pull out the Valkyrie Rockets, and then their equipment.

While the player is sw itching between the two, there will be a short period of time while the player has out no weapon or equipment. During this time, the player must quickly switch back to their Valkyrie Rockets. The player will then have no weapon, cross-hairs, or hands in their view. In third person, the player's character will be holding a knife that seems to be floating in mid-air. To actually do the zombie walk, the player must walk forward slowly. From third person, it will appear that the player is walking in a manner that is similar to that of zombies.

Theater Continuity Glitches
Status: CONFIRMED (Xbox 360)

Details: There are several inconsistencies when rendering a video through theater. Sometimes, the effects of flashbangs will not appear in a rendered video, though it appears in the original file share video. Also, sometimes vehicles that are destroyed during the rendered video will appear to be on fire before it is destroyed.

Juggernog Downing Glitch
Status: CONFIRMED/UNPATCHED (Xbox 360)

Details: In Kino Der Toten, if the player gets downed while drinking Juggernog when the bottle is not visible, the player will have the perk when downed. When the player gets revived, the perk symbol will be visible but it will still take two hits to get downed.

Graphic glitch
Status: CONFIRMED/UNPATCHED (PS3/Xbox 360/PC)

Details: This glitch can happen when viewing a killcam or when in theatre mode. It does not affect gameplay though. If there is an unexploded car in the map, and something happens so the car explodes. and is left to burnt scraps of metal, it appears to already be destroyed if reviewing a former clip of gameplay. In other words, the car doesn't exploded again but merely bounces from the ground, when reviewed in theatre or in the final killcam. This also happens with exploding barrels. Another example is in "Launch". If the game ends just before the rocket takes off, and the final killcam occurs in the area beneath the rocket. The killcam will show a departing or departed rocket even though when the gameplay happened, the rocket was still there.

Ascension invincibility glitch
Status: CONFIRMED / PATCHED (PS3, unconfirmed on other consoles.)

Details: This glitch happens on Zombies map Ascension. The player must have either PhD Flopper or Juggernog. A player must be at the lunar lander near the PhD Flopper. One must quickly buy the lander, but back out before it launches. Once the gate on the lander comes up, while crouching, one must move forward and be between the end segments of the gate. When done correctly, the player will be rising with the lander but be able to jump off at will. Once the lander stops ascending and pauses before moving towards the lander station, the player must jump off. The player will now be on a ledge of a building, where no zombies can even notice the player. For a more effective use of the glitch, the player should jump down to the lower ledge accessible from the original ledge. Zombies will notice the player and run toward him but will just circle the player since he is too high for the zombies to attack. Jumping off the lander at different times can cause the player to be in other invincibility spots, but in some places the player will not be able to leave the spot. This glitch has been patched. When someone attempts this glitch, after reaching a certain height, the player will completely die in mid-air and will respawn next round.

Escalation Wager Match Glitch
Status: CONFIRMED (Xbox 360)

Details: Sometimes, when voting on a map in a Wager Match mode other than High Roller, maps from the Escalation Map Pack will have a different game mode than selected. If chosen, the different game mode will start. For example, if Sharpshooter is selected on Weekend Gambler, the vote icon for Zoo may say Gun Game, and that will be the game mode played. Other maps will have the right game mode.

Shangri-La: Staying at PaP
Status: CONFIRMED WITH 2+ PEOPLE (Xbox 360)

Details: Open Pack-A-Punch by standing on the tiles around the map. After it's opened, have a player prone on the left side of the machine (as close as possible). Then move the Left analog stick to the furthest right, and the Right analog stick to the furthest left. When the water comes down, they player should not be affected by the water. After the water has finished falling or when other players have been sent down, the player is able to stand up and be unaffected by the gushing water, allowing the player to stay at the top of Pack-A-Punch machine.

(Note: This will stop when PaP is opened again. It will only carry on if the player stays prone in the corner each time another player goes to PaP)

No Model Glitch In Killcam
Status: CONFIRMED (PS3, unconfirmed in other consoles.)

Details: After winning a match and getting a game-winning killcam in multiplayer mode (most often in Search and Destroy), the character model shown to die in that killcam will disappear. It is unknown how this can happen that the character model will disappear, but getting a game-winning killcam will result in that glitch. This can also be seen while using the recording mode and replaying it in Theater.

Hellhound Glitch
Status: CONFIRMED

Details: It makes it so that the Hellhounds will just stand in front of the player and not attack them if the player is on top of a chair next to the automatic turret in the theater room of Kino der Toten. The player must be floating in the chair for this glitch to work.

Zombies Sound Solo Glitch
Status: CONFIRMED (Xbox 360)

When playing any DLC Zombies Map on solo, and the player gets signed out of his/her gamertag during the game, the characters wont make any quotes, no perk jingles will play, Announcers will not say anything at the start or during a round, or during the Easter Eggs. The demonic announcer will not say anything (like in Nacht Der Untoten) when a powerup is dropped. The player will only hear "lander incoming" and the sound effects on Ascension. Also, the player can't hear any Hidden Songs while it is activated and playing. SFX sound will work as normal, so gun noises, and other SFX noises, can still be heard. Occasionally, the Voice announcing the Excavators on Moon, can be heard. Other times, the SFX will not work as well when in Area 51, and it will change back and forth between turning on and off staying there for a long while.

Some maps might not even make sounds coming from the Zombies, including Call of the Dead.

Villa Orange Glitch
Status: CONFIRMED (Xbox and PS3)

On the map Villa, in the villa itself, there is a flying orange in the center of the house, under it is a small counter with other food.

Moon Excavator Glitch
Status: CONFIRMED (PS3 unknown on other consoles)

On the Zombies map Moon the excavators may sometimes glitch in a number of different ways. One way may see the excavator begin to come down and when the player hacks the console the voice announces control has been restored, when in actual fact the excavator stays down and the large saw on the front disappears. When this occurs it is impossible for the player to pass through tunnel 6 or 11 without being downed, however the bio-dome can still be entered with the PES. Another way may see the same scenario occur, however in this case the excavator rises and goes back to its position, but the large saw still moves down (it will still be attached to the body of the excavator), at the end of the time limit it stops descending and the appropriate section will be breached, showing the excavator in its beginning position but still active and the section impassable (confirmed for tunnel 6 only). It is possible that during this glitch the same excavator can breach again, in this case the player can make the tunnel passable again if they wait for the time limit to end before hacking the console. However during this the excavator saw will descend into the ground, and if it breaches once again after this then the tunnel will be impassable for the remainder of the game.

Chrome Glitch
Status: Most likely patched / Unknown

Call of Duty: Modern Warfare 3
Zero gravity glitch

Status: CONFIRMED (On PS3, unknown for others)

Detail; On the mission Turbulance, the player should pick up an AK-74u as soon the enemies breach the conference room. Then, during the "Zero Gravity" sequence, wait until you are close up and kill enemies (With the AK-74u), and if and enemy is killed in the right location, he will drop an AK-74u that can be picked up. Then they have to switch to the five-seven and pick up dropped AK (Whilst in mid-air). When back on the ground, you will only have one AK-74u. Pick up the five seven and it will be held as if still in mid-air. This will last until the pistol is dropped. (They may have to retry a few times because an enemy might not die close enough to pick up their weapon)

Campaign Completed Over 100%
Status: CONFIRMED (Xbox 360, PS3)

Detail: Upon complete completion of the Campaign (Veteran and all Intel acquired), the percentage may state that the player is "100.3% Complete" with the Campaign mode.

Sniper Glitch
Status: CONFIRMED / UNPATCHED (Xbox 360; nonfunctional on PC, unknown for PS3 and Wii)

Detail: To do this glitch, the player needs a sniper rifle and aim down the scope. Once finished aiming, knife to an enemy while still scoped in and go back away. Then knife again and quickly switch to the equipment. Source

Counter: Try to avoid players who are using this glitch as they're more likely to use explosives and knives. The perks Extreme Conditioning will evade the user of the glitch while Blast Shield will protect the player from explosive damage produced by the glitcher's explosives.

One Handed Gun Glitch
Detail: The player must have overkill, any gun as a primary weapon (excluding riot shield or model 1887), and a PM-9 HAMR as the secondary weapon. They must switch to the PM-9 HAMR, aim down the sight, and switch weapons (Y for Xbox, Triangle for PS3). If performed correctly, the primary weapon should be held with one hand. This glitch also works with your secondary being any assault rifle with grenade launcher or hybrid sight or shotgun

Care packages and Sentry Guns don't count glitch
Detail: Calling in a Sentry Gun or Care Package sometimes doesn't count towards the Sentry Gun or Care Package challenges

Invisible Claymore Glitch
Detail: Players can make their claymore invisible by planting them on top of a Trophy System and then removing the Trophy System, which will make the claymore invisible.

Akimbo Pistols Glitch
Detail: With some pistols, when having Akimbo as an attachment, one can fire fully-automatically. To do so, the player has to make the right-hand weapon have only 1 bullet left and press both triggers and switch weapons at the same time. This will make the left-hand weapon fire automatically right before changing weapons.

Invisible and Unusable UGL on Machine Pistol Glitch
Detail: If you have an Underbarrel Grenade Launcher on an Assault Rifle, rarely if you switch from your Underbarrel Grenade Launcher to your Machine Pistol, there will be an unusable and invisble on your secondary.

RFOM Glitch (Call of Duty 4: Modern Warfare, Call of Duty: World at War and Modern Warfare 2)
Status - CONFIRMED/UNPATCHED

Platform - PS3 only

Detail: Lets the player bypass any Call of Duty patch on all 3 current games and remain online, these players can then play with other by-passers online and in private matches. They are able to do glitches that have been patched, various hacks and play deleted game modes such as 3rd Person Cage Match. Users delete their patches and sign in and out repeatedly until they, eventually, stay signed in.

Counter: Don't be a by-passer.

Airborne Challenge Glitch
Status - CONFIRMED

Details: There are certain spots in Call of Duty 4: Modern Warfare, Call of Duty: World at War, and Call of Duty: Modern Warfare 2 in which players become stuck in a spot where players are not supposed to be able to stand, causing them to fall in place until they either die or the round ends. These spots can be used to get the Airborne challenge, which requires the player to get a two kill streak with bullets while in midair. Since the player is technically falling, the game considers them to be in midair while in such spots.

Counter: There is really no reason to counter this glitch, as it is not advantageous to the enemy.

Zombie Walk Glitch
Status - CONFIRMED

Details: The Zombie Walk Glitch allows players to walk like a zombie. To use it, a player must get UAV recon/recon plane,/spy plane and use a class with claymores/Bouncing Betties. The player plants the two claymores/bouncing betties, and as soon as the second one is planted, they call in the UAV. Their weapon will not appear. By walking extremely slowly, they are unarmed, but in third person, they are walking like a zombie. This is the animation for walking without a weapon.

Counter: Not much of a reason to counter this glitch, as it is just a visual glitch.

Close Up Reload
Status - CONFIRMED

Details: This glitch, found in all guns in World at War, but only some guns in Black Ops (e.g. the Ray Gun), allows the player to aim down the sights of their weapon while the gun is being reloaded. First, the player must press the reload button, sprint for 1 second, and stop immediately, and then hold down the ADS button. The player will see their gun up close while reloading. This does not work for empty reloads, and does not actually reload the player's weapon, it just shows the animation.

Counter: Just don't do the glitch; merely visual.

Multiple Attachments Glitch (Black Ops and Modern Warfare 3)
Status - CONFIRMED

Details: This glitch occasionally makes appear on the ground weapons equipped with every attachment at once, even ones that wouldn't normally be possible to use on that gun. These weapons, however, cannot be picked up.
