This is an amazing Mod Menu infection for COD: WAW Multiplayer not Zombies Multiplayer, regular Multiplayer. These Mods never wear off! Until you go to the Dashboard.
These Mods work in Private match and in Publc Match. If you are the host of the game in public or private, you will be able to use everything in the mod menu. But if you are not host you will only be able to use God Mode (Infinite Health).
If you are not Host you can enable God Mode by going to "Fun Menu" and press X. A small text should appear somewhere on the screen. It should say "God Mode Enabled".
