Sigma Team has unleashed a new game which is essentially another sequel to Alien Shooter, but with zombies populating the dark corners of each level instead of the usual variety of extraterrestrials. The demo limits your playing time, but cheat do allow players to take the weapons (old and new) for a test run.

For serious AS fans only. [source: Indie Games Group]
