Even though you aren't able to see them, quite a handful of weapons have a description when selecting them in the blackmarket. Installing this mod will allow you to see those forbidden descriptions.

Put the "Allow Weapons Descriptions" folder in mods. If you don't want to see a mish-mash of broken strings and left-overs you can either put the "Weapon Description Template" folder in mods and edit localisation.lua, or install one of these :

• Basic Weapon Description
• Y.A.W.N. Mod
• Maybe someone else will release something, who knows

Note : Even though this will not conflict with Extra Flavorful Inventory or any other mod that adds back weapon descriptions, there's no point in having this mod installed alongside them as they use the exact same code (or at the very least should be).
Note 2: The description in the thumbnail isn't included, you'll need to install W&ERT to see that or wait until I release its descriptions as a standalone mod which is probably going to be like in a quadrillion years.
