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).
For a little bit of flair, gave the barrel design a touch of Quake-I motif.
