Now that I think about it I can't think of a cooler map then the Nostromo in space, all the creepy corridors, and the tunnels, would also be cool seeing the mess hall, and other recognizable rooms from the film.
Same with the Alien 3 prison as in AvP2, but the Nostromo in space would be beyond awesome.. not even sure if a map like that is doable, would be a very hard map for preds no jumping whatsoever.
I personally can't wait to see some footage of a queen.. you know there's gonna be one..
