1. Berserker Box Mod

MODDB page is more interesting than the mod itself. There's an obvious question with these 'HD' mods that look worse than the original, what goes on into the brain of someone who feels throwing a bunch of filters and turning textures into a grainy, plastic-looking mess while also shooting down framerate faster than if you ripped your graphic card out of your rig is a good idea? And here we've got the inkling of an answer, with a project page that looks like the ravings of a mad man, starting with a demented rant greeting you with a picture of a new unrelated Wolfenstein game. The Doom comic has nothing on this.

Berserker Box Mod

I don't know much of the berseker mod even when i had in the past other than is based on the Quake2xp sourceport. But in any case i would recommend you to give yamagi quake II a try, in my opinion is the best sourceport, its features are giving you the most close to default experience but supporting widescreen resolutions like 1080p or higher chance of OGG music among other things.Again, i don't know much about that berserker mod other that has the the most advance graphical effects but to my taste isn't worth it.But you already downloaded so the obvious thing to do is ckeck info for both the berserker and quake2xp on google and find any instructions on the author's page.
