We've seen countless video games based on the Aliens franchise over the years, both for arcade and for home, and while they may have been exciting, they're hardly the sort of thing that we'd call in-depth. In fact, the closest we could come to feeling like we were in a true Aliens experience comes down to two games -- the 1990 Konami arcade game and last year's Nintendo DS release Aliens: Infestation. But that'll change this fall when Gearbox, the studio behind Borderlands, will team up with Sega for Aliens: Colonial Marines, a game that really dials in the feeling of the 1986 James Cameron cinematic classic.
