One of the best gaming experiences the Xbox 360 can deliver.
In my opinion
the BEST thing on
Call of Duty: World at War.
There have been four maps so far. The first being Nacht Der Untoten which is shipped with the game. Zombie Verrückt the second map , Shi No Numa, the third map pack and the fourth being Der Riese. The last 3 are
downloaded content which have to be purchased from your console.
If you are looking to into buying any of them the order i would get them in is Shi No Numa > Der Riese > Zombie Verrückt. Shi No Numa is Easier, More fun and will give you most playing time out of the 3.
There are rumours of a fifth and final map but as these are mere rumours i shall not go into detail about it.
