Sorry to bump this thread again it's just this game is stunningly good, I've now just got to the "level where your inside the worm", very very impressive, some of the best GFX's I've ever seen, and the level design leading up to that point is very good, and the section just before that "where the city sinks into that massive hole", such a cool idea to help integrate something new into that area of the game.
For anyone that hasn't played this game yet, you need to, trust me, and I'm a PS3 fan through and through, the price you can get 360's these days you just have no excuse really.
