Aliens : Colonial Marines

Meet Lt. Joseph Henry; the son of one of the most influential politicians on Earth, a proud member of the Colonial Marines, and a poor slob in a heap of trouble. Lt. Henry, after yet again being charged with insubordination, is put in command of a platoon of the absolute worst Marines in the sector and assigned the lowest detail in the corp -- checking up on a toxic waste dump! What Lt. Henry and company don't know is that this mission is about to go from bad to worse, because a strangely organized batch of Aliens has taken over the waste dump!
