Just finished Call of Duty: World at War on the 360.
Pretty good campaign although I think if you're going to do a WWII game now, you should maybe choose some different locations than the tried and tested ones.
Something I did quite like was the fact that for half the game you are running around with a flamethrower torching enemies but for the other half of the campaign you are running shit scared whenever a German flamethrower team turns up. It's an interesting twist.
Also just started the Nazi Zombies mode. It looks like it could be great fun, especially in coop!
