Glitches

A glitch, otherwise known as a "bug" or "fault", is an unexpected error in game play that causes an unintentional outcome, whether good or bad. Using glitches to get an advantage in online multiplayer is often considered cheating, and may result in a boot from the match.

M12 Firing Glitch

 * Possibly exclusive to the Gamecube.
 * Having already played this level prior enough to know what happens ahead of time is essential to pulling this off.

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 go 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 round the front, however if you go round the back there is a window the player can see an enemy through. If you try to attack the soldier in anyway with any weapon he will not notice you or take any damage. However when you see 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 bi-pod the game will play the reloading sound, but not reload. After the sound plays, the weapon will reload. This is because the game tries to play the reloading animation and the getting up 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.

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.

Another little known Last Stand glitch involves your grenades. If you are holding a stun or flash grenade when you are hit by bullets and knocked into Last Stand, the stun/flash grenade you were holding will turn into a fragmentation grenade and explode, killing anyone near you and yourself. A big bonus to this in Team Deathmatch and other games that depend on kill count is that it takes the kill from the person from the opposite team and makes it a suicide instead, not giving them the points for the kill.

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, get up the low wall next to it until your on the top of the outer wall. Walk along it to the left and then turn right and jump for a low roof. The jump should be easy and you will most likely make it first try, but if not, keep trying and aim at the satellite dish on the low roof. Then jump off on the other side and you will be in a previously inaccessible part of the map, the same area you can see from the roof of the station just before you find out Al-Asad's broadcast is a looping tape in the mission. From here walk up the hill near the station and continue until you see the concrete river bed. You should recognize much of this terrain from the helicopter entry part of the level. Walk along the concrete river bed until you see a white pipe. DO NOT FALL IN. It is rather hard to get back out. Walk across the white pipe and jump through the fence on the other side. Once on the other side take a right and walk past the two buildings on your left. Around the corner you will see a mounted M2 Browning Machine Gun mounted on nothing. It is most likely here from the truck firing at you from the helicopter part of the level. Feel free to use the gun to fire away. Look this up on YouTube as the travel to it is rather complex to follow in writing. If you play on PC you can simply use the "noclip" cheat.

Airborne Glitch
This glitch allows you get the challenge called "Airborne." The way it works is by playing in Crash and going north to where a tall building with 3 stories is. There, you need to exit the building from the second floor side, where the ladder to the third floor is. Once out there, you will see a blue barrel next to some stairs. What you need to do is run toward the barrel, jump, and then go prone right in front of the barrel. Then, you'll notice that your character will start to look up by itself. Once it's sight goes all the way up (your gun should be pointing almost at the sky), press the button to jump twice. You should be standing up, but any enemy will see you as if you were crouching. Now, all you need to do is shoot two enemies, one after the other one. You can do this in Cage Match much easier.

Pipeline Glitch
In Pipeline, go to the building across from the one with the opening to let you out on the awning. Outside on the wall you will see a box, crouch under it and either stand up or jump.

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, an easy glitch is present. The player must immediately jump backwards when able to move out of his/her damaged vehicle. This action will make you fall off the bridge. On the way down, the game may save your progress as a checkpoint while still falling. The first fall, you will die, but when you respawn at your airborne checkpoint, you will land on the riverbed alive. There, the player may wander along, and be able to exit the map via multiple terrain holes. If so, the player is able to see the entire level. The helicopter scripted to fire at you still carries out the command, so be careful because you may 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, but 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 you get the chance to crawl out the vehicle. It is hard because you are at the very edge of the bridge and subject to falling.

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 you will not go through the door Vasquez is supposed to open.

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
This glitch makes the player be launched into the air. To do this have a friend on the opposite team stand a few feet on the other side of a slanted object. Touch the object and try to bayonet your friend. The glitch was patched for PS3/360/PC, yet a few glitch spots remain.

Breaking Point
On the last American campaign mission, sometimes instead of Roebuck or Polonsky giving either Roebuck's dog-tag and vice-versa you are still capable of moving around, however still minus your weapon. You are also unable to venture in to other areas of the courtyard only the areas available when battling the Japanese in the final showdown.

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 by April, 2009. Video:

Three Gun Glitch (Nazi Zombies)
Zombie Verruckt: To do this glitch, you must have the power on, enough points, Bouncing Betties, and maybe one last zombie to keep the round going and to save you time. You can put the first Betty wherever you want. Then go to the desired Perk-A-Cola machine. Hold down the button that places the Betty, but don't let go. Once you drop the Betty, press the action button to buy the cola. If you did this correct, your character will not have any gun, so you can buy one off the wall or get one from the box. Once you have purchased a weapon you can keep on switching guns and will notice that you have your new weapon and your old ones which will make three weapons. You can keep on doing this glitch for more than three weapons. This means that if you have all the perks, you will have to go down and get revived again to do the glitch another 4 times.

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

Der Riese: There are several methods, however most require at least 2 players to perform. One only requires one, however. To do this, you need the power on, the 3 teleporters linked, Bouncing Betties, and at least 5200 points. First, leave a crawler, since this glitch takes some time. Put one of your 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 your Bouncing Betties by pressing right on the D-Pad. The moment the Bettie comes up, take your gun from the Pack-A-Punch machine. This will allow you to keep all 3 guns. However, you cannot do this to get more than 3.

Note that once you have every weapon that is obtainable, the Box will only hand out the Colt M1911!

'''Be sure to keep the last crawler or zombie occupied so it doesn't get people down. Have at least one person the zombie can follow. Switch players when people are ready so that everyone has a chance at getting what they want.'''

No Weapon Glitch (Nazi Zombies)
In Der Riese, if you buy a Bowie Knife and get downed, you will have no weapon when you get revived. However, you can get it back by pressing the weapon switch button.

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. Though it's 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. It has no beneficial effect on the player at all. (Tested once, worked). Proof |Here

Counter: Release equipment button, die, press Change weapon (Triangle, Y, 1 or 2).

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

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

Counter: The enemies will still shoot you even though you are outside the building, so don't let your guard down, although there is plenty of cover.

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

Details: In the campaign mission Whiskey Hotel when you get across 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 force you to turn the system off manually, to make matters even more annoying the freeze occurs before any checkpoint, this is more common on Hardened editions of the game.

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

Fast and Slow-Mode Games
Status: Confirmed/Active (Xbox 360) (March 5/20)

Details: There is a mod off the internet that lets players be able to host public fast or slow-mode games. This is usually combined with other mods to make it a very fast and very annoying game.

Counter: Most people just leave the game thinking it is the game, but you must turn off your console. This becomes a problem, because a player will quit and not turn off the console and might end up being host, thus the glitch will continue.

Shooting Equipment
Status: CONFIRMED / PATCHED

Details: While in multiplayer, a player can use One Man Army Pro, and a Tactical Insertion. You have your One Man Army selection menu open, ready to select another class. At the same time select your class and hit your Equipment button to launch your tactical insertion. It will look like you are planting your tactical insertion while changing class. if done right, you'll run around looking like your about to use your equipment (hold a claymore, throw a fragmentation grenade, etc.) This works with all equipment except Blast Shield. For Tactical Insertions, you'll have a broken model of the flare. Every time you shoot, you run the cap over the fuse, like you're planting the flare over and over. For claymores, you hold the claymore out like your going to plant it. When you shoot, it appears as if you are planting the claymore repeatedly. For C4, you'll hold the detonator, every time you shoot, you'll appear to throw the C4. And for Semtex, Throwing Knife, and Frag Grenade, you'll look like you're throwing something over and over, like a pitching machine. This does not affect accuracy, damage, or anything with the gun. if you fall from a high height, sprint, throw your equipment or special grenade, or run out of ammo for a gun, then switch back to that gun, the glitch will reverse itself and you will have your gun back. This is merely for fun, however you must be level 45 to use OMA (One Man Army). Another funny glitch is to pull out an RPG-7, with the Claymore as your equipment, while the above glitch is active. When you fire, in 3rd person, you'll look like your doing curls. The equipment glitches with the weapon, therefore causing you to appear like your planting a claymore over and over, with the RPG stuck sideways across your arms. This also prevents you from firing the RPG.

Minigun 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 using ADS on a mounted minigun. It does not affect the minigun's performance at all. Furthermore, while using a sniper rifle, and using ADS: the Minimap radar disappears, as though you are using the scope of the sniper rifle. Another glitch is being able to use a riot shield while firing the minigun. First, use One Man Army to change to a riot shield class. While changing, use the minigun and you will have a Riot Shield in front of you. There is also another way to do this glitch, and anyone can do it. In the beginning of the match there is a bit of time to switch classes once the game has started, if you're close enough to the minigun, you can pause, go to change classes and pick one with a riot shield, it will have the same effect of doing it with One Man Army. One of the benefits of this is that anyone can do it, and you don't have to be level 45.

Details: Also, you can use a Javelin and aim until it beeps. When it does so, get on the Minigun, and the Javelin should fire automatically. When viewed in Spectator, It'll fly more forward and higher than the usual up-and-down fashion. It'll also travel farther than usual. It's most noticeable in Wasteland.

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.

Multiplayer Launcher 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 you must first change to your launcher, then hold your equipment button down so you take out your equipment, and finally while still holding the equipment button switch back to your launcher and release the equipment button when you feel a light ping. As long as you have your launcher out when you are killed you will explode, even if you knife an enemy. It is amusing to do this with the RPG-7 because it makes your rocket act like a mine, it will shoot the rocket downwards and will stay there until someone hits it. The most common and preferred launcher and equipment to perform this glitch with was the Javelin and Semtex before it was patched. This issue, (more commonly known as the "Javelin Glitch") 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 Unlimited Ammo Glitch
Status: CONFIRMED / ACTIVE for all platforms.

Details: In Team Deathmatch, players will have unlimited ammo. Guns, grenade launchers, launchers, and even the AC-130 are automatics. Its very rare for people to get into these kinds of lobbies

Counter: Turn off console or stop iw4mp.exe because the glitch stays.

10th Prestige Mod in Modern Warfare 2
Status: CONFIRMED / Attempted Patch (FEB 7)

Details: Recently discovered, a program allows players to make a game into a modded game in which each kill is worth a large random number of EXP. This is has been patched on the PC and is currently in testing for console users. Most people will take advantage of people who want 10th prestige early and ask for Microsoft points or a large number of headshots but when given them they will simply leave the game.

Infinity Ward attempted to patch these lobbies by removing the host migration in the lobbies so they could only last for about 36 hours at the most. These lobbies are still going on but be wary because most of them are used to scam people for 1600 Microsoft points or membership. They may also be "De-rank" lobbies to take your rank AWAY when you get a kill, so be careful!!

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

Details: As of the recent "Javelin glitch" update patch, it is possible to glitch the server 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 your overall score. Players who have accepted the latest update for the game are unable to do this anymore, they will just receive a message saying "Unable to join game session".

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

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.

Counter: N/A

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

Details: If one uses up an attachment (such as the M203) then the player will be able to use their main weapon as if they had gone prone or obtained the Final Stand deathstreak. This can also be done while switching classes with One Man Army, then in Last Stand you will be able to use your switched class's main weapon.

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. If you put them in last stand, do not underestimate their ability to bring you down with them. Flanking works best, as does tossing a flashbang or stun grenade after you've 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: If one gets any of the care package Killstreaks, approaches a surface that says "Press A(X on PS3; F on PC) to jump," and put the smoke signal in your hands. Press A(X/F) to begin climbing over the obstacle, tap "right" on the d-pad twice before you finish climbing (hard to do if using Marathon Pro). If done right you should still have the signal in your hands. Throw the signal, pick up the package, call in whatever was in it (ammo doesn't work), then you should have another package waiting to be called in. You must do the glitch each time you try to throw the marker otherwise it will stop glitching. This can be repeated continuously throughout the game, even if you die. This glitch is often considered a "noobish" or "cheap" way to get a high number of kills without actively participating in the objective. The glitch can be seen here. If you feel the need to do this glitch, moderation is key, as it will prevent others from being aware of your activities. 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 he D-pad at the same time. You will capture the care package and have a care package marker in your hand. To repeat, throw the beacon and use the killstreak. The glitch will stop if you use it on an ammo resupply or die.

Unresponsive Multiplayer Glitch
Status: CONFIRMED (PS3) / PATCHED sometime in December 2009

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 will 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 Helicopter. Then, when the player will go into the small house where the Squad finds cover, the player will Automatically gain an M4A1 and an M9. Feel free to exchange the three weapons you have for any other weapon on the ground, you WILL keep all the weapons. If you get very lucky, it is possible to get a TAR-21 with an actual Red Dot Sight, rather than a MARS Sight.

Counter: N/A

Assault Rifle Camouflage Glitch
Status - CONFIRMED

Details: If one makes 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, an interesting 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, choose the first class, then select the other class. Then kill yourself somehow, and after you respawn with the other class, go pick the other assault rifle up, switching it for your secondary. Now 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. There is a useful video of this glitch 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 a 9 kill streak and calls in a Pave Low, then the kills the Pave Low earns do not count on the player's kill streak count. There is also a glitch where if you get a Pave Low from a Care Package, the kills 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 AT-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.The XP gained from this has been patched but it can still be used to get cold blooded pro fast

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 his or her OMA pack and a host migration occurs during the selection, the player will be stuck with his OMA Pack as his weapon unable to switch weapons. You can use your knife, it is unknown if equipment can be used.

Counter: Just die from the enemy or leave game. Both will make you return back to normal. An easier thing to do is just go to the start menu and select "choose class", then just select whatever class you have on now and you'll be back to normal.

No Weapon Glitch
Status - CONFIRMED

Detail: If you go to the weapon selection screen right when you die, it is possible that you will respawn with nothing on the screen. When you fire, it will look like you are switching to your weapon repeatedly.

Counter: Don't go to the weapon selection screen right when you die.

Reload glitch
Status - Confirmed

Detail: When firing a weapon full-auto, if the player presses reload while he/she fires, the gun will reload and two Extra rounds will be added to the magazine.

Counter: Kill the player when they stop shooting to prevent the reload glitch.

Riot Shield Glitch
Status - Confirmed

Detail: If the player melees with a riot shield and holds a throwing knife, then reload cancels, then melees again, they will hit twice at double the normal speed.

Predator Glitch
Status: CONFIRMED

Details: If a Host Migration occurs while a Predator Missile is being called in, the Predator Missile will fly straight down and explode uselessly during the 5-second waiting time. Even if it hits a player, it won't damage them, since all players are invincible until the game restarts. However, it rarely happens when the game puts the player back before they got the Predator Missile, so then they can get the fifth kill and get the Predator Missile again.

Details: There is a second one. If the player has just pulled up the Predator Missile laptop (must be before the missile fires) or right after the missile detonates (laptop can't be put away yet) and there's a host migration, there is a rare chance that after the migration, the player will be stuck with the laptop up when wielding their primary weapon, and will be armed with their primary weapon in one hand, and their other hand will be dangling in the air when the secondary weapon is selected.

Counter: There is no counter for this, since a Host Migration can occur at any time.

Attachment Glitch
Status: UNCONFIRMED

Details: Sometimes in the level Team Player, when the player is killed and respawns, he will be given the same weapon, but with every attachment available for that weapon, allowing for assault rifles to have multiple sights, and multiple under-barrel weapons.

Source: Unconfirmed gameplay

No Russian AI Glitch
Status: UNCONFIRMED Details: If you kill the FSB in the level No Russian before they enter the elevator, the script can't have Makarov kill them with a grenade, and will freeze all AI, which will cause them to not shoot unless you fire at someone. In addition, the AI will call you a coward, traitor, and betrayer, and break the freeze to kill you. While you can fight them back, their health will prove this to be very difficult. Source

Spawn Reload Glitch
Status: CONFIRMED

Details: Often, if you are killed during the middle of reloading you will respawn with the reload animation still playing, but 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.

Keep Custom Classes After Prestiging Glitch
Status: CONFIRMED/PATCHED

Details: Ability to retain your custom classes after prestiging by moving the up arrow on the analog stick followed by pressing a or x and selecting prestige through the split screen offline mode.

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 than be enabled during online play instead of achieving the required prestige 13.

Grim Reaper Glitch
Status: CONFIRMED/PATCHED (Replaced by RPG-7)

Details: Sometimes, when killed while reloading the Grim Reaper, the player will spawn with their Grim Reaper constantly keep on 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, especially Gun Game.

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 "Hands Off the Merchandise". The glitch has been patched by the inability to let the player onto the second plank. Also, you can unpatch it on the Xbox.

Prestiging in Combat Training
Status: CONFIRMED/PATCHED

Details: This glitch enables the player to prestige after reaching maximum level, and more than once, but is only for Xbox 360 (There may be a second glitch for PS3, however). 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 x 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
Details: This is not a glitch, but some people believe it to be, so it is listed here. It 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 should have the camouflage that you wanted.

Video Walkthrough

Zombie Walk Glitch
Details: To do this glitch, you have to get Valkyrie Rockets from a Care Package or from the actual killstreak. All you have to do is get equipment. Pull out the Valkyrie Rockets and equipment until you have no weapon, crosshair, and hands in your view, it's just plain empty. In 3rd person, if you do this glitch right you will hear a beep and your character will be holding a knife in mid-air. To actually do the zombie walk, you have to walk slowly by pressing the trigger slightly without crouching/proning. While your switching between the missiles and equipment and your Primary/Secondary weapon keeps poping up, then you are doing it wrong.

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.

Zombies downing glitch
Status: CONFIRMED/UNPATCHED (PS3/ XBOX/ PC) Details: if a player lies prone in the corner of the lobby in kino der toten, the corner near the zombie spawn, on the opposite side of the quick revive machine, and the player dolphin dives onto the player who is prone, both the players are downed instantly.

Graphic glitch
Status: CONFIRMED/UNPATCHED (PS3/ XBOX/ 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.

ADS Animation Glitch
Status - CONFIRMED

Platform - Nintendo DS only

Detail: Enter the Training Room and there will be a cinder block wall behind the instructor who talks to you when you 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. It may take a couple of tries before it works, and when it works you will know. As soon as you sprint or enter and exit ADS mode again your gun will return to normal. This glitch works with all guns except the M40A3 and the crossbow.

Counter: N/A

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, and use a class with claymores/Bouncing Betties. The player plants the two claymores, 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.

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 you to zoom in while your gun is reloading, as if aiming down the sights, at nothing. First, you press the reload button, sprint for 1 second, and stop immediately, and then hold in the ADS button, and you can see your gun up close while reloading. This does not work for empty reloads, and does not actually reload your gun, it just shows the animation.
