Me and my friend were playing on world at war and i was on the cat walk at derice with a wonder waffle and i had set some bouncing betties for protection because my friend was covering the stairwell and i was taking out big crowd of zombies and i look over and zombies are just blowing up in my face set so many bouncing betties i had 8 gimps by the end
My highest level I've ever gotten to on any maps is level 48 on Kino Der Toten. In the 40's, it gets to the point where even your ray gun takes 5-8 shots to kill a zombie. And the length of the rounds are ridiculous.
Never bought the other maps, so I only remember Kino and Five. On both I use the typical strategy; gather a lot of points, get the drinks, get the important guns, and run around in a circle. Such as the MP40/MP5, RPK/other light machine gun, and the thundergun/freezegun. The first two are to gather points while the last two are going to get you out of trouble, in case you're trapped. Sometimes when I got bored of this I would mix it up, like pistols only and other silly things like that.
you never bought any map packs ghost? for shame! they are amazing, not so much shangri la for zombies anyway, the multiplayer maps in that map pack was great, but the zombie map is really hard, call of the dead is probably the best zombie map to date followed by moon, then ascension then shangri la
