Clean Breach has a similar objective to the CleanTF2, (from Team Fortress 2) to make textures clean and light, so that the game can load faster and (maybe) get a better FPS. By clean i mean turning an white concrete wall into an completely white wall.
And by light, i mean reducing an texture's size. An example:
173's normal texture is of 269KB, i took it and reduced it to 44,4KB.
The size of the concrete wall (concretewall.jpg) is of 383KB, i took it and reduced it to 25,3KB.
Here are some screenshots of this mod:




Currently there is no download link, but i will post it when i at least cleaned some of the items, the hud, 049 and 079.
