Like promised ZPS was released Dec 28th 2007 (PST). We welcome you all to join in and enjoy the mod we worked so hard to release to you.
Please visit the Website for Mirrors and links to a Known issues list. This is our first public beta so there are still some issues to solve but we are already working on a future patch and a content expansion!
For those interested in mapping, MapMan went ahead and tossed this Mapping Guide together for you all: http://www.zombiepanic.org/tutorial/
Thanks,
