Cabelas, If you download the UMOD version of the IMTWP, it could do all the work by itself, but I guess in the .zip version there´s a readme.txt to help.. anyway, .u and .int files are supposed to be put in the UnrealTournament/system folder... perhaps you put in the INF/system folder, that doesn´t work..{=(
And you have to put it in the active mutators list, when you´re playing INF...
