Storyline

The alien invaders from Alien Shooter have quickly become the dominant species on the surface of Earth. Humanity has had to hole up in protected and contained settlements. For over a year people have had to learn to live in these settlements and have become their own prisoners. But now a group of scientists have come up with an experiment to fight back and resist the invasion from decimating the human race. This plan calls for the creation of a super creature who, under control of humans, will fight the alien invaders and push them back. It's up to you to find this creature and set it free to fight the menace, but of course who's to say The Experiment won't backfire?
