Cyrgoth's Manor is a 7 level singleplayer WAD for HEXEN, designed for GZDoom and Zandronum. It was also designed with Co-op in mind and the maps are also optimized for deathmatching modes as well. It contains 1 secret level in addition to the 6 mandatory levels. There are secrets in this WAD, however, like in Hexen, they are unmarked, so good luck finding all of them!
