There are some great Post-apoc games out there , but I havent seen a sourcebook like this. A Post-apoc city, 200 pages. Full of awesomeness. 108 illustrations, 5 maps, dozens of charts, 122 locations, and much more. Its made for the Mutant Epoch game, but could very easily be used for Mutant Future or any other PA game.
I highly recommend it.
