This is a graphical mod developed by a russian modder called Berserker. It's an active project since 2008. The mods purpose is to enchange Quake2's graphics.
Very good mod, graphics evolved like god, I liked the new effects placed in the game. but I missed an option of physical attack that could be placed. (like a punch, kick or a punch using his gun) and put the flash on weapons and some more details, otherwise I would note instead of 10 ^ ^
