This is some awesome work, some things I noticed.
When I entered the bar, I got some crashes due to missing textures. L85, some crosshair, and some gun name I forgot. The textures where in the textures\wpn folder, but they had a suffix of "-n". I deleted the "-n" and the game picked them up fine.
Also, I love seeing the different weapons on NPCs. Some placement is odd, there are lots of MP5s still about. I can't help but think a high-end SMG like that wouldn't be so common, more bizons, mac10s, and tec9s would be more fitting. The placement of unique weapons is awesome. I got this awesome AK74su from Bes, and the tactical AK in Strelok's stash is neat too. The sounds are great, and the textures are great too. The weapons all look professional, the don't stand out as amateur or modded in.
Great work on the weapon descriptions too. Very entertaining and informative. I also like how at a glance I can check caliber, special features, and compatible upgrades.
