Alwin on Prey [Xbox 360], 02-11-2006
"Looks like a standard FPS like Doom or Quake but it isn't. The ability to change the gravity really changes the game, it's not just a gimmick. There are some cool puzzles based on switching the gravity to the floor, then the left wall, the ceiling, etc... and back again.
I have completed Prey and the entire game was fun to do, it was never annoying or boring (which is quite rare I think). The story helped keeping me interested, though I though the "indian theme" was a bit far-fetched.
Finally, what I liked most about Prey is that you do not die, never ever. Yes, sounds strange, because one would think it would make the game very easy. But it doesn't, the game is still hard enough. It just keeps you from having to do the same sections over and over again (which always annoys the @#$% out of me). When your health reaches zero you just go to a heaven-like place where you have to shoot red and blue birds for about 15 seconds, each hit giving you some health back. After that, you return to the exact same place and situation that you were in before, even during boss fights."
