1) First of all you must installed C&C Generals & C&C Generals Zero Hour. 2) Make sure you remove other mods before applying this one. 3) Extract the two zip/Rar files into C&C Generals Zero Hour game folder. Default folder should look like this [ c:/program files/EA games/ Command & conquer generals zero hour ].
4) After applying this mod, the game will execute a lot slower & began to crash. Its okay, you just need to launch the game again & it should be fine.
