Radiation

Radiation is a multiplayer map, featured in Call of Duty: Black Ops. It is set in an abandoned power station. The map features a conveyer belt, where if the player does not jump off in time, they will meet a fiery death. There is also a trap door, like a silo hatch, that can be opened and closed via a switch located some distance away. Anyone that falls into the trap door dies from a fall-death.
