I've been very interested since that Game Informer cover story way back when. A squad based tactical FPS set months after Aliens and with modern tech they can actually make the aliens AI work just like how they act in the movies. That just sounds amazing. I haven't played many squad based shooters but I still play SWAT 4 from time to time, as long as nobody in Colonial Marines says "You're in my way, sir." I won't have a problem.
