P.E.S

The P.E.S. (Pressurized External Suit) is a piece of equipment on the Zombies map, Moon. Right after teleporting to the moon, it is in front of the player and is avaliable for free. It is also available in every Air Lock on the map. Without the P.E.S, the player has only about 15 seconds to survive in an area without oxygen. You can also trade it for the Hacker.

Trivia[]

You can still drink Perk-a-Colas while you are wearing the helmet.
Contary to belief, it does not replace Claymores.
