Whilst the Zombie Panic team is busy slaving away at the next patch, I would like to make the announcement that the HL2 Zombie Modification, No More Room in Hell has just been released.
It is a multiplayer, 8 player co-operative survival horror game with a focus on semi-realism. It was inspired by the "Of The Dead" zombie franchises.

Several members of the ZPS team were also involved in the development of this mod over the past 2 years, so enjoy the mod and report bugs on the NMRiH website at
