Alien Cabal

When it began few people noticed. A near doubling of UFO sightings over the city. But the local media dismissed them as hoaxed, military tests, or overzealous UFO fanatics. They were wrong. The UFO's were real. Aliens had been visiting for some time, studying mankind and earth's resources.

Now they were planning an invasion.

Your mission is simple. Find the entrance to the underground complex, exterminate all alien life, and destroy everything else. Don't be fooled by what appear to be government agents. These are clones programmed by the aliens to serve their purposes.
