Based on the Aliens movie, Aliens: Colonial Marines, developed by Gearbox Software, is a squad-based first-person shooter where players are part of a United States Colonial Marine squad and must prepare to face an Aliens assault more intense and horrific than ever before. When SEGA
announced Aliens vs. Predator and delayed Colonial Marines, speculations were that it got canceled, but SEGA confirmed that it's still in development, as well as
Obisidian's RPG. The reason for neither game's appearance at E3 was that AvP is coming this year, the others most likely not, with
CM getting a DS version but not by Gearbox.
