bought kane and lynch 2, and i can't really understand why it got so slated. Sure it's an obvious console port (althought it got bad reviews on console too), and the controls/cover system/ AI need some work - but it's a very enjoyable game, the grittyness of it is a nice change from todays flashiness and whatnot, the film-like story and player camera are a really nice effect, the graphics range from average to fantastic, and I'm really looking forward to the arcade/multiplayer modes once I've finished the single player because they really bring something new and interesting to multiplayer shooters. I bought it for a fiver and it's worth it.
A good way to describe it would be Mafia 2's cover/shoot gameplay, for an entire game. If you loved the shooting bits in mafia 2 but felt they were underused, as I did, then you might want to give this a go.
