it's not easy. i think it's one of the hardest mods to install.
Download and install Metamod, then sourcemod, configure sourcemod how you want it, then download zombiereloaded (plugin from sourcemd) and its requirements (like SDKhooks if i am not wrong).
Configure your zombiereloaded configuration (it takes around 2 hours for a newbie).
Don't forget that there is a forum that supports all this, we don't.
Ok but which ZombieMod has the EliteHunterz Server
isnt there zm 3.0?
Please Answer this: Can you guys do it for me...
