Sounds like this one could be a winner for Rebellion, although I'm not too sure about the idea of changing perspectives after each level. It worked OK for the King Kong game 4 years ago, but after playing the last AVP PC games, I would have preferred them setting it out as separate campaigns. If they can strike a decent balance with the levels (one third of them Pred, one third Alien and one third Marine at least), I won't mind it.
