It's hard to tell from my screenshot, but this texture patch gives you textures that are psuedo 1960's. At least that is how they looked to me. The best set of textures in the bunch seemed to be the pfhor group. Alot of Peter Max looking swirls and neons combine to give you a completely different world of Marathon. Worth the download if for no other reason than to just check out another authors perspective.
