Corridor 7: Alien Invasion

The year is 2012. A team of U.S. scientists returns from Mars with a small, metallic object - the first hard proof that life exists beyond our planet. Rushed to a top secret underground facility, through a maze-like series of hallways and test chambers, the object is secured in the lowest level laboratory - at the end of Corridor 7. Subjected to gamma radiation, the sphere explodes - transformed into a radiating gateway, linking our world with another. An army of creatures emerges from the pulsating vortex. The Alien Invasion has begun. You are a Special Forces Agent, sent to eliminate all invaders, floor by floor - by whatever means possible. Wage a ferocious battle through the overrun military base and reach your destination. Down Corridor 7 looms the fate of the entire human race.
