Nazi Zombies is great. I got to level 22 by myself on the first one, and level 29 on the second one with friends. I have already reserved COD: MW2. It looks to be GREAT. ONE THING thats unforgiveable (To me) on COD5: One of their biggest mistakes is right on the disk!! look at the thompson he is holding. You can't see an ejection port, which must mean it's on the left side of the gun, which is HIGHLY un-likely, especially during WW2 times. So ok, the guns made for a lefty.....except the shooters still using it right handed!! which means when he shoots all of the hot shells are flying out and hitting him in the face....They really didn't think this one out very well.
