Alien Resurrection didn't need that to scare the living shit out of you, or to be very hard, even on easy difficulty setting. That being said I'm also ok with certain liberties as long as they enhance the gameplay in a meaningful way, but at this point any speculation is rather pointless until we actually get to play the game. I'm pretty sure I'll enjoy it regardless, I just want it to feel like a mature, smart and proper Aliens experience and not a juvenile wank or over-excessive fan service.
