Moon

"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. (JFK, 1961)"

- Moon Description

Moon is the eleventh Zombie map and the last one included for Call of Duty: Black Ops, featured in the Rezurrection map pack. It was released on August 23 for Xbox 360 and September 22 on PS3 and PC. The original characters return in this map. Moon is the largest Zombies map in Call of Duty: Black Ops, and the second largest in the series after Green Run.

Overview
Taking place in Area 51 and on the Moon itself, this map is a challenge for all players. Tank Dempsey, Nikolai Belinski, Takeo Masaki, and Edward Richtofen return as playable characters, as well as being able to play as Samantha Maxis as part of an easter egg. Two new Wonder Weapons make their debut: the Wave Gun and the Quantum Entanglement Device, with the Gersch Device replacing the Monkey Bomb from other maps. Two new pieces of equipment also make their debut: the P.E.S. and the Hacker device. The P.E.S. allows the player to survive in areas which have no oxygen, while the Hacker device allows the player to hack various objects to produce a wide assortment of effects. Two new Zombies are featured in this map: the Astronaut Zombie and the Phasing Zombie; the Astronaut Zombie will walk around slowly, and if it can grab the player, it teleports the player randomly to places they have opened and also taking a perk, while the Phasing Zombies are an advanced version of the Crawler Zombies, which can teleport short distances towards the player. Phasing Zombies have less health than Crawler Zombies, whereas the Astronaut Zombie has massive health, similar to the Napalm Zombie.

Spawning in Area 51, zombies will spawn with low health and speed, and gradually become stronger and faster as time increases. Two sounds will be heard, a soft beeping and then an alarm similar to that of the Tactical Nuke sounds to alert the player(s) each time the zombies gain more health. Hellhounds will spawn with the zombies, with a max of 10 able to spawn at once. Juggernog or Speed Cola will randomly spawn here, alternating each time the player travels to Area 51. If players are overwhelmed, they can fall back to the teleporter, where they will be sent to the Receiving Area, on the moon. To fully activate the teleporter, every player in the game must stand on it. When first arriving, artificial oxygen will not be available, making a P.E.S. necessary to survive, a P.E.S. station will be directly in front of the player when they get teleported. Unlike the previous maps, there will not be any weapons in the "spawn room", needing to open another door to access the M14 and the Olympia, along with two more spawn areas, with the "spawn room" only having two windows. Once the power has been restored, artificial gravity will be restored inside the buildings. However, oxygen can be removed by either Excavators, or if they player breaks a window with explosives in laboratories or spawn room. Any locations that have no oxygen have also low gravity.

Note that Area 51 does not feature rounds, instead it will last until the players die or use the teleporter, with the zombies getting stronger as time goes by.

New Perk
Mule Kick is the new perk on this map, located near the Teleporter and the AK-74u. It costs 4000 points and lets the player carry three weapons. The player will then have to purchase the third weapon off the wall or from the Mystery Box.

Locations and oxygen levels
Oxygen is not present in any areas until the power switch is turned on. Once this is done, oxygen still is not constant throughout the Griffin Station, and can be removed by various factors in the game. If the oxygen is removed, the announcer can be heard saying "Warning: Major decompression on (location). P.E.S. required.".
 * Area 51: The default spawn; Area 51. There is nothing to purchase here, with the exception of either Juggernog or Speed Cola (alternates each time when the player enters) and Pack-A-Punch. A teleporter is located here for access to the moon. It is easy to hoard zombies here because of the open space, allowing people to have early Juggernog or Speed Cola since the power is always on here.
 * Receiving Bay: This is where the player teleports to after leaving Area 51. It contains the P.E.S, two doors, which cost 750 points (buying one of the doors opens the other too), two windows, Quick Revive and, next to this one, a Mystery Box spawn. It also has three panels that, when used with Hacker, deactivate the excavators. If Excavators Pi and Omicron are activated (Tunnel 6 and 11), and one player gets downed here while the other are on the other side, he/she can get the One Giant Leap achievement/trophy upon respawn.
 * Outside Receiving Bay: The next accessible area after leaving the Receiving Bay. There is a launch pad to take the player back in,and consoles for playing "Samantha Says," necessary for Richtofen's Grand Scheme. There are two tunnels accessible from here. There is also a huge trench where the three rockets that blow up earth in Richtofen's Grand Scheme. If you jump into this via one of the two openings, you will be downed and killed instantly. There is no oxygen here.
 * Tunnel 6: A purple-walled area with a confusing pathway from one end to the other. It is a cheap, fast route to activate the power and find an MPL and M16. Zombies are able to spawn in the ceiling here. There is oxygen here, but an excavator can remove it. This tunnel must be breached during Richtofen's Grand Scheme.
 * Tunnel 11: A much more expensive route than Tunnel 6, but contains Stamin-Up and Semtex grenades, along with a PM63. There is oxygen here, but an excavator can remove it.
 * Power Room: The room unlocked after exiting either tunnel. The pyramid in which Samantha will spawn during the Easter Egg is located here. Right below the pyramid, there is the power switch. A Mystery Box spawn is in this room. There is no oxygen here. Players can purchase a Stakeout here.
 * Laboratories: Three floors accessed from the Power Room. The first two are unlocked using a single door, the third must be unlocked for another 1000 points. The Hacker may spawn on a desk located in any of these stories. There is oxygen here, but it can escape if an explosive shatters glass. Double Tap Root Beer is located on the first floor and Deadshot Daiquiri is located on the third floor.
 * Outside: Accessed from third floor of laboratory. The teleporter back to the receiving area is here. Inside the teleporter is a small gap in which you slip down into the Power Room, useful as a shortcut or escape. There is no oxygen here. A Mystery Box spawn is here. Mule Kick is located here. To the right of Mule Kick on the wall, there is a AK-74u available for purchase for 1200 points.
 * Bio-Dome: Also accessed from the third floor of the labs. Launch Pads are in this room, which can transport the player from side to side. Power-Ups spawn between the Launch Pads, which players can acquire if they jump on the pad. A Mystery Box spawn is here, as is oxygen, but it can be removed by an excavator. PhD Flopper is across from the mystery box, across from the entrance to the labs. There is also a door players can open which leads to the teleporter area.

 * The fourth musical easter egg is an 8-bit version of Coming Home. It is not required that Re-Damned be previously activated . It can be activated by pressing X (or square) on the radio at the end of Tunnel 11 on top of some computer equipment near the power room door.
 * The fifth musical easter egg is an 8-bit version of Pareidolia, it is activated by obtaining a Film Reel and pressing the "use" button near a computer in the labs, and can only be heard in close proximity to the terminal.
 * A major easter egg, Richtofen's Grand Scheme.
 * Bio-hole easter egg, hidden hole in the Bio-dome to get under it but zombies can get in. Not sure if it is a major one but depends.
