"Five"

"The Pentagon is under attack! Washington is going to DEFCON 1 in this installment of "Zombies"."

- "Five" description.

"Five" is the second of four zombie maps in Call of Duty: Black Ops. The map is unlocked after finishing the campaign on any difficulty, or typing "3ARC UNLOCK" on the computer via the main menu. This map is set in the Pentagon. On February 18, 2011 Treyarch's community manager Josh Olin announced on Twitter that "Five", along with Dead Ops Arcade no longer need to be unlocked by finishing the campaign.

Characters
"Five" features four significant real-life figures from the Cold War era:
 * John F. Kennedy - 35th President of the United States (1961–1963)
 * Robert McNamara - U.S. Secretary of Defense. (1961–1968)
 * Fidel Castro - Prime Minister of Cuba (1959–1976), President of Cuba (1976–2008)
 * Richard Nixon - U.S. Presidential Candidate (1960), 37th President of the United States (1969–1974)

Boardroom (Starting room)
This room contains 4 windows and two sections of wall that can be broken down. It contains the Quick Revive machine and a telephone required for the musical easter egg. It also contains a teleporter (active only after the power has been turned on), the Olympia, and M14 available for purchase off the wall, both for 500 points. In solo the Quick Revive will disappear after three uses, effectively giving the player four "lives" as long as the player keeps returning to the machine. When the power is turned on, this room gets very dark, and the lights are either dimmed or flickering. Of the 6 spawns, in the very first room, only 4 spawns are used; however, these spawn points change when the power is turned on.

Hallway
This room is the only one that connects to the starting room. There are two doors that lead to this room; both will open when one is bought. It contains two windows and two sections of wall that can be broken down. It also contains the first elevator which takes the player down to the war room. This room also has Speed Cola, and an MPL available for purchase from the wall for 1000 points.

First Elevator
To access it, one must remove a barricade blocking it (costing 1000 points). Trips cost 250 points (both up and down). Zombies can get into the elevator to attack you and your teammates. There is little room to navigate in the elevator, so even a few zombies getting in can be devastating. With it being small when a zombie attacks it can trap you into a corner, glitch inside the Player, and kill the Player. The flames that appear are getting rid of the already killed zombies inside the elevator.

War Room
This room is the biggest actual room in the level, split into different sections. The first elevator takes the player to the top floor of the War Room which contains four windows, an MP5K and PM63 (1000 points each), and the Double Tap Root Beer machine. The player must then buy access to the bottom floor of the war room for 1000 points. The bottom floor is divided by two barriers that must be bought for 1250 points each. It also contains the Juggernog machine, a Stakeout (1500 points), and the second elevator that takes the player down to the lab area. This room is connected to the bunker and contains the four switches that must be flipped to decrease the DEFCON level to DEFCON 5, which makes all teleporters go to the Pack-A-Punch room/Panic Room. It also contains a teleporter. It also contains the trap box that can be placed in your inventory and later used in the top floor metal detectors. The top level of the War Room is the room where players are usually killed because occasionally someone will not guard a window, which will result in a break in. Smart players should have everyone take a window to stop this problem or (not recommended) elevator camp, just make sure everyone is in the elevator. Those in front can crouch and take care of the big mess while the two behind them and clean up and revive if necessary. The bottom level of the war room can be taken care of easily if you stay together. Buy/Clear the two barriers and walk out of the zombies reach in a circle, all the zombies will bunch up in a horde making it easier and faster to kill them. It is recommended not to run while doing this as it ruins the cycle and the horde will divide. Cargo Elevator This elevator is much larger than the first and has a window on each level to make camping in the elevator more difficult. It also faces different ways depending on which level it's on. This elevator, like the first, cost 250 points to use between trips. Zombies can swarm players in this elevator easily as well. If several zombies become trapped in the elevator between floors it is possible to run around them in circles until the doors open again, assuming you have Juggernog.

Lab Area
This area is made up of hallways and rooms and is accessed by the elevator from the War Room. It contains the power switch and a telephone required for the musical easter egg. Once the Lab Area is accessed, gas zombies will spawn (only while a player is in the Lab Area), teleporters and Perk-a-Cola machines will be activated, the DEFCON level can be changed, and the path to the Bunker is available. The area itself contains several teleporters. The M16 and the AK-74u (1200 points each) can also be purchased in the Lab Area.

Testing Room
This room seems to have been a testing room as there is a live pig hanging from a crane which can be killed and some human corpses, very similar to the Nova 6 test subjects in "Rebirth" (Implying America got hold of Nova 6 and Reznov was correct that whoever got hold of Nova 6 would still use it). Claymores and a Mystery Box spawn are located here. It also contains two windows, and several doors. Also, one of the bodies in the room is confirmed as Sgt. Roebuck from Call of Duty: World at War, possibly saying he ended his life as a test subject, or he was just in this room when the zombies attacked and killed him.

Weapons Testing Room
This room seems to be used for Testing, as there is an unusable Winter's Howl, Thundergun and a Death Machine. There is one Mystery Box spawn and the Bowie Knife is located in there. This room is closer to the Teleporters that return them to the same floor level of the Labs, albeit on the other side of the Labs. One of the trap pieces can be found in a locker in this room. There is a glitch were you can break down the window (nearest to the teleporter) with the Bowie Knife and then stand, where the window used to be, and then just keep on shooting. (You can still get Power-Ups)

Conference Room/Panic Room/Pack-A-Punch Room/Room 115
The 115 Clearance Room is attached to the War Room and can be accessed once the power is turned on and DEFCON switches are decreased to 5. It contains one of the telephones required for the musical easter egg and the Pack-a-Punch Machine. It also contains two windows and a teleporter. It is seen in the Level "U.S.D.D." when Mason talks to John F. Kennedy.

Thief Round
In "Five", a thief round will occur some time after round six, as long as the power has been turned on. After the first appearance, the thief round will occur from then on every four-eight rounds. Like the Hellhounds, this is a special round with no regular zombies. Unlike the Hellhounds, the Thief cannot down the player. The thief will chase after the player, and upon catching them, will take the gun the player has equipped. This can be excruciating in later rounds, especially if the player has a high-powered and/or Pack-A-Punched gun equipped. The thief will run around through the teleporters, until reaching the teleporter which brings the player to the starting room, upon which the thief vanishes. The player can kill the thief, or fail and see their gun disappear. The Thief is not attracted to monkey bombs. Aim for the head if you trust your marksmanship. Killing the thief after he steals a weapon will result in all weapons returned, Max Ammo, and a Fire Sale. Killing him before he steals anyones weapons will result in a Max Ammo, and a Bonfire Sale, which is like a Fire Sale but it also links all teleporters to the Pack-a-Punch room and drops the price to 1000 points. Not killing the thief will only result in a Max Ammo. He will only appear after the power is turned on. It is best to find which player the thief is chasing so that player can run around on the middle floor. Other players that are not targeted can shoot him down without being at risk of any weapons being taken. The Thief will appear as a cloud of red numbers to each player until they are targeted by him. Once a player has been targeted, he will be visible to that player until he either escapes or dies. (see pentagon thief)

DEFCON
Another major gameplay element of this map is the DEFCON (Defense Readiness Condition) feature. In the main room of the Pentagon, there are a series of switches that will decrease the Pentagon's DEFCON level. After hitting four switches, and putting the Pentagon at DEFCON 5, a secret "panic room" will open up. This room contains the Pack-a-Punch machine. The Pack-a-Punch room will close once everyone has left the "panic room". To open it again, the DEFCON must be lowered to five again. The room will remain open as long as one player is in the room but when the doors are open the Pack-a-Punch Machine disappears. The DEFCON system is one of the only ways to access the Pack-a-Punch on this map. When DEFCON is lowered, ALL teleporters will go directly to the Pack-a-Punch room. Don't all go in through the teleporter at once or the player(s) will be downed. The only other way to get in the panic room is the Bonfire Sale power-up, negating the use of the DEFCON switches to get in.

Trivia

 * This is the first map in which zombies can use teleporters without dying
 * All of the characters have suits with sleeves up to the hand on in third person view, but they have arms similar to Tank Dempsey's in first person view.
 * If a player is downed on one floor, and his/her teammate(s) take an elevator up/down, they can see the zombies in the level that they are downed in disappear into a ball of electricity, respawning in the level that the rest of the team is in, or they float up in the air.
 * Usually the characters being played as tap their foot in impatience while waiting inside for the elevator to open again. This can be seen when playing with two or more players.
 * The name Five refers to both the DEFCON levels and the sides of the Pentagon.
 * Coincidentally, this map also marks the appearance of the fifth Wonder Weapon, the Winter's Howl.
 * This is the first zombie map to take place in the United States.
 * If the player tries to enter the panic room before going through the DEFCON levels, the player will be denied access and the text: "115 Clearance Required" will appear at the bottom of the screen. This is reference to Ununpentium, also known as Element 115.
 * In the hallway, there are several pictures referencing Call of Duty: World at War, such as a plaque mentioning the battle of Peleliu, and Sgt. Roebuck at the Battle of Peleliu.
 * It seems that the Wunderwaffe DG-2 was originally supposed to be in the map, as there are unused sound files of the characters' reactions to getting the Wunderwaffe from the Mystery Box.
 * It is the first map that players can destroy a barrier.
 * If you go near a DEFCON switch while having the power on, the text will read "Press (X/F/Square) to lower death-con level."
 * There are clocks on the wall where you spawn. They show New York, Hong Kong, Hanoi, and Moscow's time. The time shown is correct.
 * On the wall next to the MPL is a picture of Major John Plaster, who provided work for Call of Duty: Black Ops.
 * There are three red telephones on this map: One at the start at the game, close to Quick Revive, one on a desk in the same room as the power switch, and the final phone is located in the Panic Room. Once all telephones are activated, "Won't Back Down" by Eminem will start to play.
 * There is a television above each Mystery Box location which can be used to locate the Mystery Box.
 * The portrait of Richtofen and the blank portrait from Kino der Toten appear in the Panic Room.
 * There are news boards with news connected to the zombies.
 * There is a unobtainable Death Machine on top of a shelf in a room on the lowest level.
 * In a room on the lowest floor there is a Winter's Howl on a table with work tools surrounding it. This strongly implies that the Winter's Howl was manufactured at the Pentagon.
 * This marks the first time in the Call of Duty franchise that the President of the United States and other high ranking characters are playable.
 * It's possible to see the base frame of an older teleporter, like the ones from Der Riese or Kino der Toten, through a zombie window in the basement, to the left of the AK74u. It could provide evidence that the US copied the technology, as the teleporters here are different. There's also a Ray Gun on a desk to the right, which might suggest they are researching or copying the gun.
 * No Gas Zombies will appear in a round if no one visits the lab section, or if no one is in the lab section and the elevator is NOT called to the second floor (Confirmed on Xbox 360 and PS3)
 * In the opening cut scene, it appears that all the clocks are set to 12:00 AM, but the ingame clocks feature the correct time. This is due to the opening scene being pre-rendered.
 * On one of the podiums in the starting room, there sits a scrap of paper that reads "Ignomo Jubilus", which is roughly translated into "Laughable Mistake".
 * On the metal detectors/traps the player can see III ARC and the Treyarch logo.
 * Any activated DEFCON switches will be de-activated at the end of a Bonfire Sale.
 * In the Pack-a-Punch Room there is a book titled Exposed. What can't be seen without noclip is that on the back is a picture of what appears to be a zombified gorilla. The text next to the picture reads "man sent the first primate into space, and it returned..." This could be both a reference to the Cosmic Silverback or to the Space Monkeys in Ascension
 * The light used to locate the Mystery Box from Der Riese can be seen if the player noclips out of the map.
 * On split screen, it is possible to hear quotes from your dead partner if you stand near enough to where they died.
 * On a chalk board in War Room, there is a list of SR-71 flights which can be presumed to be wrecks.
 * It is possible to only have a knife. The way to do this is in a thief round if you only have one gun, he will take it. This will cause you to knife extremely fast.
 * Any Zombies that are in the small elevator while it is moving will die as if killed by a Fire Pit.
 * In the lab section of the basement, canisters of Nova 6 can be found.
 * If you look at the screen near a mystery box spawn point and look at the televsion above, you may see the Eye of Providence.
