Unbelievable that it’s been a year since I’ve last updated this page. My how time flies. By popular request, I’ve updated the map list with a bunch of new maps. It’s in a PAK file so all you have to do is download it, unzip it and plop it into your quake\baseq2 directory. If you already have a pak5.pak file, just change the number to something else. Get the new pak file here.
2018 update: Download the full set of files for Plague Devastation including the updated, full-featured game engine (from R1ch.net), from my CloudFront distribution.
