tiberium wars campaign maps

[Jthe420]

anybody know how to get ahold of the campaign maps in C&C3? it seems the xcc mixer doesnt work for that game.

or maybe its cause i got it from steam? either way how do i change the maps? and the OS Big editor doesnt do anyhting...or at least it isnt in the game folder thats in documents....theres no regular game folder for it. theres a application icon but idk where that even leads to at this point.
