This topic is not, I repeat not, about treyarch's popular nazi zombies. This topic is for any dicussion, tips, anything about nazi zombies portable, a game designed entirely off nazi zombies but using an extremely changed quake engine. It's extremely fun, and serves as a great game on the PC or the PSP(doesn' even need CFW!). They have map making setups and plenty of online communities. Currently it's in beta testing and can be downloaded at http://www.moddb.com/games/nazi-zombies-portable/downloads
its totally free, and has tons of user made maps for download. Its a nice little game to play if your ever bored.
If you do try it out it can support multiplayer, basic instructions for this can be found here: http://nzpmaps.forumotion.com/t48-how-to-play-online-without-hamachi-in-3-easy-steps-found-by-skawng OR here: http://nzpmaps.forumotion.com/t11-how-to-play-online-in-4-easy-steps-pc-only
