SInce I never kept my original Rainbow Six Vegas 2 saves, when I reinstalled the game I found myself with most of my equipment locked. This means I will only be able to tweak the basic unlocked weapons for the first few updates, and will then add more advanced weapons as I progress in the game.
I'm probably going to finish Menus UI before I'm done with all the weapons, so I will probably release an Equipment and Interface only version of the mod as soon as I'm done with those. This will let you play the game with the overhauled UI, but without an inconsistent weapon behaviour.
