While Sega has yet to officially confirm the status of its Aliens RPG, a designer that used to work on the project has said it was canned.
David Kondor's online CV states he was "Designer for canceled third-person action Aliens RPG (Xbox 360, PS3, & PC)".
Aside from the original announcement Sega never really gave out much more on the project. Kondor's CV pretty much wraps the case up but we've contacted Sega for comment. You know, just in case...
Earlier this month Sega revealed it would publish a brand new Alien vs. Predator game in collaboration with Twentieth Century Fox. hit the link above for more on that.
