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.
This is definitely THE mod for Q2!
Can't live without it.
when you play as, for example, a cyborg, you hear cyborg sounds! It's THAT detailed!
It has flashlight that can eat cells! ( Personally, when I start a new game, I come close to Bitterman's pod and I give myself 50 cells. It must be enough till Jail levels. After all, Bitterman could've rip out battery from his pod, right? ;-)
And, from time to time, I just start a new game to marvel at new gibs logic (AMAZING!)
And it works under linux(wine) flawlessly!
Also, mod creator is a very helpful person. When I complained about game getting too easy for me after years of slaying Stroggs, he just've send me modified DLL that allows to adjust enemies damage scale!
Thanks for that!
