"The players control a squad of space Marines in charge of freeing a command post overrun by alien forces." Each player controls a landing party of six marines, consisting of one leader, one sergeant, and four soldiers. Each marine has a randomly determined set of skills. Available skills include xeno-biology, computer, mechanics, ground navigation, and morale. The parties must travel from the drop zone to the overrun command post. Inside the command post is the Alien Queen which must be defeated. The party must then return to the drop zone with the Alien Queen Brain. Played using the WarpQuest game system.
