When u go on to ur start menu and u highlight battle for middle earth, u will have a list of options. one of them is map builder or something like that. Click on it and then u can build ur map

Im confused,book says u hav to download it on to a file,wat start menu the one when u put in the disk that screen comes on or the one that goes up after the story?

first, on your computer, go to your program files. then, find EA games. enter that folder,
double-click Battle for Middle-Earth, and select the Worldbuilder program. that's all you
need to do.

How do you set units our buildings on your map ?
