Marine Doom

Marine Doom is a 1996 modification of the first-person shooter Doom II for US Marines, which was later made available for download to the public.

In the game, a fireteam, comprising four Marines, is supposed to accomplish a specific mission, the default being the destruction of an enemy bunker, although other scenarios such as a hostage rescue in a foreign embassy can be designed. In order to allow coordination of their movements, these soldiers play on separated computers in the same room. The fireteam consists of a team leader, two riflemen and one machine-gunner.
