Dont do it,i have been playing this game since the beginning and let me tell you this game sucks. you run around figure out a few puzzles that are irrelevent.Then you mash buttons again and again,then you beat the game and thats that. unless your into doing the samething over and over go for it but in my opinion its terrible.
To me this GOW wasn't as good as GOW3 but the gameplay is defintely better. The storyline not so good but every thing else is really amazing. This also might be the hardest one of them all. So if you thought the other GOW games was easy this might give you a challenge.
