Gameplay
Corridor 7 consists of 30 floors (with 40 floors in the CD version) and 6 bonus floors. The player is tasked with killing a certain number of enemies before the exit to the next floor is accessible. There are four difficulty settings, which modify the number of enemies that need to be eliminated and how much damage the player will take from enemy attacks and traps. In the CD version, there is a fifth setting ("President") which randomly scatters items and enemies throughout the game.
The player can activate the proximity map in one corner of the screen, showing a small section of the current level with active aliens marked in yellow. The map can be expanded by finding the floor plan.
Story
The staff of a top-secret research laboratory, Corridor 7, inadvertently opens an interdimensional portal known as the Vortex while experimenting on an alien artifact recovered from Mars. Shortly after, hostile aliens emerge from the Vortex and kill all of the staff. The player, as a lone special forces soldier, enters the base to fight the aliens and destroy the artifact, thereby closing the Vortex.
Reception
Corridor 7 received mixed reviews at launch. Chris Anderson of PC Zone stated that the game offered "nothing new and what is there isn't very exciting", and largely criticized its use of the Wolfenstein 3D engine.
Legacy
Corridor 8: Galactic Wars was the planned sequel to Corridor 7. The game was in development and used the Build engine, though it was never finished because the developer, Capstone Software, went bankrupt along with their parent company, IntraCorp, in 1996. The game only made it to prototype stage. In 2005, Les Bird sent the Corridor 8 prototype source code to a Corridor 7 fan, who put it onto his website as a free download.
