Taking place just after the events in the movie Aliens 3, Sega's Aliens: Colonial Marines puts you in the combat boots of a United States Colonial Marine in this co-operative squad-based tactical shooter. Explore the abandoned USMS Sulaco and the planet LV-426 with its wrecked alien spacecraft as seen in the first two movies. Go beyond the movies as your mission takes you to futuristic cities on other planets.

With a plot written by Battlestar Galactica and Star Trek: DS9 writers David Weddle and Bradley Thompson, and using the Unreal Engine, players find themselves immersed in claustrophobic environs as part of a four-man Marine squad with sudden death lurking nearby. Play solo in command of your squad – with the ability to shift from Marine to Marine - or take on the aliens with three other friends with drop-in/drop-out cooperative play.

Each Marine has unique weapons, skills and duties as well as specific mission objectives. The familiar M4A1 pulse rifle and M240 flamethrower will be close at hand as will other favorites and some new equipment as well. The aliens have different classes as well and will respond differently to situations and threats – they won't just throw themselves into the path of your M56 Smart gun. The hunters will be the hunted.
