i dont care what people say this was one of the best ones

Pros:

good map

REALY HARD!

bots handle the campaign pretty amazingly

good amount of zombies

hard but worth the download

nothing

 the campaign was amazing i was astonished on how fantastic everything looked especially the new weapons could you do wore campaigns like with other weapons?
