I was looking through fpsbanana today and chanced upon some maps that i saw. These guys take regular maps and update the textures and models and the result is absolutely amazing. . D1 and d2 look pretty damned good. Here are some of the maps they’ve done:
their was i group of ppl that did this for 1.6 awile back,, they were de_mapname_1337 minor changes but mostly just textures.. They were a fun just for a mixup of seeing the same thing ovr and ova.
