Eternal Darkness:100 New Levels For Quake addon

Running Quake levels takes some effort but it can be done quickly this way: Take the BSP file you want to run out, Place it in the Quake directory under Maps if you have the Steam release, otherwise take the BSP and drop in in the directory under Game data.

Running mods requires you to place the Files in their own file under Quake's Addons file, Then move sounds and animations to Quakes base file.
