Power Switch

Most Zombie maps a Power Switch to find in order to open certain doors, activate Perk-a-Cola machines, and other features that may be unique to that map, such as the Zipline, or Teleporters.

Trivia

 * The Power was introduced in the map Zombie Verrückt, which was the second Nazi Zombies map.
 * Shi No Numa, while it did feature the power, it was not required to power up the entire map, as Perk-a-Cola machines and traps are all usable from the start. The only part of the map effected by turning on the power is the Zipline.

Appearances
The power feature appears in all canon zombie maps besides Nacht der Untoten and most fanon zombie maps.
