The guys from Zombie Horde have announced version 1.0 of their mod for Counter-Strike: Source:
The team at zombiehorde.com are proud to present Zombie Horde v1.0, the often imitated premier Zombification plugin for Counter-Strike Source.
Since April 2005 we have been bringing the zombies to the Counter Strike scene for all to enjoy, this release is the culmination of two years work, and is vastly improved for better performance and greater compatibility with all server types.
At long last we have hit the 1.0 milestone. Like the undead, Zombie Horde has once again been resurrected to fight another day. After a long time of no updates, we are excited to release not only the Source Metamod versions of this great plugin, but also long sought after windows versions too!
