Call of Duty 4: Modern Warfare Mod Tools

Currently, Cod4 Mod tools are only supported for the English version of the game
Activision has released the English version of Call of Duty 4: Modern Warfare Mod Tools, a package which allows you to create modifications for this popular first person sequel developed by Infinity Ward. Note that CoD4 Mod Tools requires your video drivers and DirectX to be up to date. For certain applications to work correctly a DX9 video card is required, even though the game itself will run on a DX8 video card. The CoD4 Mod Tools do not work in Windows Vista, although some users have reported some success running them in Windows XP Compatibility Mode.
