If players are overwhelmed, they can fall back to the teleporter where they will be sent to the Receiving Bay at Griffin Station, on the moon. Juggernog or Speed Cola will randomly spawn, alternating each time the player travels to Area 51, and at the beginning of each game.

Hellhounds will spawn randomly with the zombies, with a maximum amount of 10 able to spawn at once. Two sounds will be heard, a buzzer which signals the access to the teleporter to go to the moon and then an alarm similar to that of the Tactical Nuke sounds to alert the players each time the zombies gain more health. Spawning in Area 51, zombies will spawn with low health and speed, as if it were round one, and gradually over time become stronger and faster as time increases. Moon features a brand new Zombie called the Astronaut Zombie, who will walk around slowly, and if it can grab the player, it teleports the player randomly to another place if they have opened the door leading towards that specific area and, only if the player bought a perk, the astronaut zombie will also steal a perk, it also has massive health, similar to the Napalm Zombie from Shangri-La. grants the player the ability to survive in locations which contain no oxygen, while the Hacker device allows the player to hack various objects throughout the map to produce a wide assortment of effects. Two new pieces of equipment also make their debut: the P.E.S. Two new Wonder Weapons make their debut: the Wave Gun and the Quantum Entanglement Device, with the Gersh Device replacing the Monkey Bomb from other maps.

Occurring in Area 51 (Also known as Groom Lake and No Man's Land) and on the Moon itself, this map is a challenge for all players. Ludvig Maxis contacts the remaining members of Ultimis through the stations electronics and asks for their help to defeat Richtofen, ultimately sending three rockets to the earth, completely breaking and shattering it. The Ultimis crew finally travel to the Griffin Station in 2025, a secret Group 935 facility on the Moon, where Richtofen completes his Grand Scheme and swaps bodies with Samantha in the M.P.D., giving him full control of the zombies and the Aether.
