This is the Wulfen Texture Pack that was extracted from Wulfen’s Doom 3 Texture Mod ported over to Garrysmod. It includes 20+ different texture styles and floor patterns, all detailed and with high resolution style just like how they are used in the game. These textures work real well for scenery wise, screenshots, sci-fi style creations, and everything else. If you have any questions, please let me know.
