Single-player megawad that pits the player against the forces of Castle Doom. I tried to keep it generic so that the various advanced ports can all run it the same way.
The authors of Doom, Risen3D, gzDoom, prBoom-plus, and Doom Builder. All the musicians that made the midi files I've included, and all the artists that made the textures. I'm not an artist/musician, and I don't claim to have made any of that content. (If anyone wants specific credits, please let me know and I'll gladly include names here.)
I believe the heretic textures I've used came from a pack made by anthraxscare (c) doomsdayhq.com, which appear to be free-to-use, at least according to the readme file.
I've also used some textures from the gothicdm, ogrodtex, and erattex1 texture packs.
Also, thanks to the great Doomers out there that make inspirational maps, such as Hell Ground, Scythe, Memento Mori, Reverie, and many more. You all rock. This is my thank you contribution to the Doom community, and I hope you enjoy it.
