Yeah, you can do it I finally figured out how to get the friggin things to work. I had unpacked my .pk4 files trying to find where the .demo files were located (I still want to make a video... ). Anywho, this morning out of boredom I tried unpacking the .pk4 files for the nitrogore (sooooo sweet) and ducttape mods; I changed the file names of the original files to "filename"_old.xxx just incase, then I put the moded files in the appropriate folders. It worked just fine. I couldn't find any info on the net about how to make the PC mods work, so I figured I'd let you fine people know incase you want to experiment.
