I really liked to play this game, it's gorgeous, the mood is absolutely fantastic. It can really be a terror experience sometimes which is awesome. The latest part of the game is absolute crap, it's the typical scenario where everything goes wrong and your character is a god. Really bad script at the end of the game, which is unfortunate. At the beginning I was loving it, but the curve kept going down. I felt that most of the gadgets and weapons were dispensable, only 3 to 4 weapons were worth using it, they could have gone more strategic options. The alien AI was a bit off, he was always around your areas despite one not doing any sound. Too forced.
Cool game though.
