Not a whole lot of Alien games have been coming out recently (whether that’s good or bad, is for you to decide), but it seems that is going to change. SEGA has acquired the rights to the Aliens franchise. An FPS and and RPG are planned for PC as well as next generation consoles (shouldn’t that be called “current generation”?).
Personally, I think these could be done well. An FPS that would utilize the Wii’s controls for some cool mini-games (like, devour marines with the tongue in tongue mouth thing using the Wiimote).
