I strongly recommend this game for owners of a PS 3.
Reviews give this game 10 or near 10, I would not give as much because, even when it is a great game, fighting is a bit repetitive since enemies are always the same - humans, humans infected (similar to zombies) and super infected blind and very aggressive, also a variation of the last type that appears a couple of times.
Some stealth is needed since provisions are limited and sometimes too many enemies can come at times if one is discovered. It is possible however to play more stealthy or more aggressively depending of one's choice.
I liked the ending, many people don't, I suspect the players that dislike it are mainly quite young. I cannot say why but if you have played it and want to know my opinion you can send me an email or a private post.
