Alien: Isolation < info here
I never heard of this game before, but now it's popping up everywhere. Being a huge Alien fan, I'm still a bit angry at Aliens: Colonial Marines, but I have hopes for this one. For starters, it's based off of Alien, not Aliens - so you have no weapons and there's only one alien hunting you down. Another thing I must mention, everything looks exactly like it did in the original - and you even have the original green-screened motion tracker.
My friends dissed the game when they saw Sega's name on it, but I still have high hopes for it.
