These bumpmaps are ripped right from TF2 and are insanely better! In-case you didn't know, those bricks are actually from TF2; just with an overlay and a few edits to the bricks. Despite that Valve decided to edit the bumpmaps a bit and downscale them. Making them look even more cartoon-y then they do in TF2.
Tired of Valve's blue brand-new looking auto shotgun? Enjoy this apocalyptic auto shotgun - which is heavily inspired by the auto shotgun shown in world models for the TRS build of "Left 4 Dead"!
