Right I just completed the pc game, and its solid, but nothing fantastic.
I especially loved the 5 second ending
anyway, just in case you are wonderin if you should get this game, its a standard shooter the whole way through, with nothing that you havent seen before [unless you consider ' slowmo' innovation]. Sound pretty crap right now ant it? but one thing that I really like about it is the horror flashs, they rock, some neat tricks are used give it a real horror felling, alltough the game isnt really a horror, often using cheap ' jump in front of the screen' stuff to scare you. At one point at the end, the single most impressive part, is a massive explosion, ever see Terminator 2? where your one had a dream about a nuke going off in the city and the blast wave comeing right to her?, well its excatly like that, and it rocked, just looked awesome.
The story, was unimpressive, I guessed what happened at the end after 30mins of playing it. Its pretty much leave your brain at the door kind of stuff, no particularly hard puzzles [I think i met one...] its a pure blaster from start to finsh, and is fun. Alltough it does get a tad boring, more variety would have been very much welcome.
The graphics look great, I played it on a 6600gt,1gb,3200+ computer and got 40-60fps, which made it a joy to play.
I recomend a ' borrow' or a ' rent' , but i wouldnt have spent full price for this game, even though it is very solid.
I expect the 360/Ps3 to be pretty much the same.
