Looking for this MOD or map or server...

[overbenwah]

I was playing on this server the other day... it was a zombie server where humans are on CT and the T's are the bot zombies. The zombies keep respawning until you kill the target amount each day.... i think there's 2 days total to get through. There are fast zombies... some kind of larger mutated zombies, some fat zombies, and these huge muscular monster zombies that look like the things from The Lord of The Rings... the ones that open the big gate in one scene. I'd love to know if there is a mod for this or if anyone knows some servers... THAT WOULD BE AWESOME. Thanks for your time and I hoe you can help. Have a good one.
