The Space Marines set down on a planet called Zeevan, and quickly encounter Gorilla Aliens birthed from the ape-like creatures indigenous to the planet. The Marines' dropship is destroyed when a stream of acid spat at it by one of the Aliens detonates the warheads on board, and the team is stranded. They make camp and successfully fight off Alien attacks, but Ripley is captured by the Gorilla Aliens and taken to their treetop Hive. With a rescue ship on site, the other Marines prepare to launch a rescue mission.
