The Laboratory Trap (also refered to as the Geistkraft Induction Tunnel) is a trap found within the Call of Duty: WWII Nazi Zombies map The Final Reich. It is located in the Laboratory and can be activated for 1000 Jolts. When activated, it will cause the entire tunnel to be filled with lightning, which will attract zombies to the machine, where they will be electrocuted to death after a short while of being within the machine.
