Corridor 7

This is a 3-D game that is sort of like Wolfenstein 3-D, Blake Stone, Doom, etc. in that you play from the point of view with the gun in front of you. The object is to destroy all of the aliens such as weird eyeball dudes and ugly monsters, then go on the elevator to finish the level. There are a variety of weapons and power ups to help you do this.

If you like 3-D games, this game might be worth a try but don't expect anything too amazing, just classic 3-D shooting action.
