It doesn't matter if the textures fit to or come from Duke Nukem, Strife, Wolfenstein, Quake or Powerslave: Everything non-Doom or non-Heretic / Hexen related goes here. Some of these textures might fit into other games as well, it just depends on the way you use them or the way you edit them. Everything should be possible, just be creative.

Most, if not all of the textures from Chasm: The Rift. The floor textures have nice names (F_******) but the wall textures do not. Chasm contained several duplicate textures, and I believe I removed most of them from this pack, though a few may have slipped through. Some of the textures were originally stretched since they would be compressed in game, those have been adjusted so that they are not stretched anymore.

All major textures from Max Payne. Some are kinda large, but could still be useful. Sorry for filesize, but some of these are big. No Playermodle textures this time around though.
