Treyarch managed to make everything but bolt actions and semi-autos overpowered.
And had the rocket launchers/satchel charges nerfed.
The only thing I liked about World At War was the campaign. I hate all of the multiplayer maps.
Also national socialist Zombies isn't that great because after like 15-20 minutes the game becomes impossible, and you just play it again to get your mouth raped 20 minutes later.
