Multiplayer
The immense success of Doom multiplayer modes is probably behind the addition of LAN and modem gameplay in the CD release of Corridor 7. The only multiplayer mode featured is deathmatch and there is also an extra set of 8 multiplayer maps included. Players can deathmatch impersonating either the Special Forces soldiers from the singleplayer mode or one of the aliens; playing as an alien results in possessing the distinctive abilities of the creature chosen (e.g. speed or endurance).
