It's so sad that project was stopped.
Frankly, this is the kind of game I want for the Aliens universe. I don't say that an excellent, so as to change FPS would not satisfy me, but frankly, if you have the rights of the Aliens movies + Prometheus, I'm quite sure you can do an excellent RPG where there is much more to do than just shooting xenos. Something with a true progression, a true story, true and complicated relationships with NPC and above all less, much less linearity. Of course, it would imply to let go the overused "I'm a colonial marine" approach, which would be lame. There would be times when you're alone, unarmed or poorly armed, stalked by just one or two aliens in a ship or a terrifying environment à la Nostromo : something that would truly make the player feel he's in a Ripley-situation, as in the first movie. The aliens would have several scenarios to follow, so as to make each play of that level quite unique, instead of the lame repetition of the alien that is spawned forever in the same place. That kind of things could add tension.
That would be a game where you can follow several paths, being gentle, neutral or evil (instead of the precedent games, where the character as a marine is always with the good guys). Where actions have consequences... etc.
