ZombieMod has been a hit for other games like Counter Strike: Source and Counter Strike, so it comes as no surprise to see one for Call of Duty 4. This should provide some basic help on installing the most popular version:
You must have the mod downloaded before you can move on, you click here to get the files 1. Stop your server from the control panel, and connect to the game servers FTP.
2. Once you've FTP'd into your server, create a directory in your 'mods' folder called zombies. You should see the mods folder in your main or root directory. (

3. Upload all of the files from the zip you've downloaded into the mods/zombies folder (
Image 2 ). Some servers execute all their files from the main folder, in which case you'll want to upload them there. This may require a command line to change to +set fs_game "mods/zombies". Ask your game server provider for help if you do not know how to or do not have access to edit command lines.
4. All of the files included serve a fundamental purpose. They have been configured, tweaked, and tested to provide the best gaming experience for this gametype. You're free to edit them how you please, however the developers and our recommendation is to leave the gameplay as is. See the official documentation for an in depth analysis of each file.
