You are the colonists of the base "Hope Hadley", into whose territory the embryos of Aliens inside its inhabitants were delivered. Hatching, Aliens begin to brutalize in the base. You managed to barricade in some rooms. The ship is already waiting for you but the docking gateway is blocked and one of your colleagues, having access to it, disappeared. An hour later the atmosphere converter will explode and it's up to you whether you can get out on this ship and avoid death.
