The fifth release of Pan-DEMON-ium, you can find versions V4 through V2 on the DoomWorld posts. (in the description)
To install, simply drag the .WAD file into your ZDoom, GZDoom, or Zandronum folder, then just drag the .WAD onto the .exe of the source port (ex. running it on zdoom would mean you drag Pan_DEMON_ium.wad onto zdoom.exe)
