Well, I once found this awesome Wolfenstein 3D mapset called Castle Totenkopf: SDL Edition, and I loved everything about it, the sound, the graphics, the levels, the weapons, just everything.

I'm asking, is there other SDL mods like that out there? Mods that use ceiling and floor textures, new detailed weapons with cool sound effects, ambient sounds, awesome music, nasty enemies, classic treasure hunting, and lots of violence and gore.
