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?
Alien Shooter: The Experiment is the second add-on to Alien Shooter. This new expansion pack adds five new missions to the game but unlike the previous expansion also introduces new playing fields such as houses, playgrounds. This expansion also adds new weapons and new enemies including a boss battle. One final addition that Sigma Team made, due to popular demand from fans, is the inclusion of a tougher difficulty level selection at the beginning of the game.
