In short, this mod page includes;Over a hundred new skins, almost all with bots of varying characteristics. Proper Weapon HD Retexture, Crosshair "improvements". Over 20 new maps of varying(amateurish) quality and theme. And some optional game-altering modifications(with each having different themes/"flavors" to choose from).
Got "Waifu2x-Caffe" (thanks to ZerterO), and the higher-poly weapon models, linked by 'girughi1533473298', which he got from 'AnimeFreak1991' of Steam, which he got from AndehX of QuakeWorld, which he ripped from Q3A-A. Motivated me on re-doing my HD Weapons Re-Texture mod.
Updated. You can now get this mod here: Moddb.com
The barrels stand to much out with their gray shade, the shotgun would look far more interesting if fully (I mean the metal parts, such as the receiver) painted in the same gray color as the middle part of the barrel. I like the plastic like grip and the pump, but their professional outlook clashes a bit with the industrial-like stripes on the barrels end, so to make it better you could make the grip darker - in a coal like color, the same as the "pump's" one.
It's only now i've read this. The whole barrel coloration thing was from the base(original) texture. So I don't want to mess with that. But i will try to do some rework on the grip's design.
