Stand-alone Marathon game. Windows version.
Fixed the gamma bug.
Awesome game! The first mission isn't easy but hey nothing should be. Is there only 3 missions? I want more missions to play!
The first time I played, an enemy came into the spawning room and would kill me in one hit the moment I respawned. Another time, I found a teleporter which took me to a room with two switches and a door that wouldn't open.
