The REVISED version of RA presents 4 times better sprites, revised weapons, realistic automatic fire and several tweaks in terms of firespeed, accuracy and firepower. Check WHAT'S NEW IN REVISED section below 'What is included' section.
This mod is COMPATIBLE WITH BEAUTIFUL DOOM v. 5.0 (or newer, NOT OLDER), but it doesn't require it, Russian Arsenal can work standalone as well. As the title implies, it's just a set of Russian firearms. And they don't look too hot. But they work. But note, that weapons with low accuracy CAN NOT be used for sniping, because low accuracy applies to each and every shot, including the first one (unlike usually in Doom), except AK-74 (its single shots are accurate). Check weapdesc.txt for more information. There's also detailed description of the guns inside DECORATE lump in the wad.
