Blue Steam Trap

The Blue Steam Trap is a trap in Call of Duty: Advanced Warfare on the Exo Zombies map Carrier. It is located on a flight of stairs, and when activated for 500 credits, either side of the stairwell will have been blocked by this blue steam. While the first one will not always kill zombies, the second one will always finish them off.
