P.E.S.

The P.E.S. (Pressurized External Suit) is a piece of equipment on the Zombies map Moon. It gives players the ability to survive in the majority of places on the Moon. The helmet is in the equipment slot and is therefore removable. The P.E.S. is free right after teleporting to the Moon, as it is right in front of the player. The suit is free to take, meaning it can easily be transferred between itself and the Hacker. It is also available in every Air Lock throughout the map. Without the P.E.S., the player only has 15 seconds to live in a low-gravity area. Neither the P.E.S or Hacker will replace Claymores.

Trivia

 * When putting the helmet on in first person, it looks exactly the same as the Gas Mask that Hudson puts on in "Rebirth", despite the helmet looking different in third person.
 * While wearing the P.E.S., the player is unaffected by the Phasing Zombie' gas, but will still be affected by the explosion of the Phasing Zombie.
 * The player can receive infinite suits from one location, despite only one being seen.
 * If the player enters an area with no oxygen, the suit says: "Please activate P.E.S. Critical oxygen levels detected." After the player puts the suit on, it says: "P.E.S. active."
 * The player can still drink perk-a-colas while wearing the helmet.
 * There is no reflection on the P.E.S. visor; it only shows a landscape on the moon, no matter where you are.
 * Some characters will call the device "pies" because "P.E.S." somewhat resembles the word "pies".
 * A common misconception is that Claymores will replace the suit, when in fact Claymores take up the right D-pad instead of the top D-pad.
 * Players can put the P.E.S in 3 different ways. A player can put it while standing, which is the regular way of putting it. If crouching the player can notice that he/she is putting the P.E.S slightly to the left. When putting the P.E.S on while prone, the player will put it on left. One of the reasons the player could be doing this is because when crouching or prone the player holds the gun in a different way, so the player does the same on the P.E.S.
