In this game the Xenos are after you. These frightening and ugly creatures have infested derelict space stations and moon bases, attacking those who cross their path. Your objective is to exterminate the hostile Aliens while collecting valuable hardware from each space station and moonbase. Trigger fast reactions and amazing joystick control are everything in this game. A whole range of hand weapons are at your disposal as you try to prevent the pests from overrunning the base. With time against you, and maybe another player too, how will you fare against Roller Baby, Snotter Pillar and other pests? Remember - watch out for Fester!
