It's pretty good. It's kind of like F.E.A.R. (both made by Monolith), except you use less of guns, and more of 2x4's and pipes that you find. Mind you, I haven't gotten too far yet, the only guns I've seen are the .45 cal pistol and the shotgun. It's one of those games that you get really into. The game has intense atmoshpere, as long as the "full screen FX" are turned on. It has a bunch of cool visual effects that makes it seem less like a game and more like a movie.
It appears briefly while you are still trying to get out of the underground complex. Does this one look familiar? And then all H_ _ _ breaks loose! And they even included a merry-go-round!
oooh, excellent, I just got to that part. I played the demo on the Xbox 360, and thought it was cool. I didnt get near as many scares from the demo, because it doesn't last to the good parts!
