The mayor thing in this update is that the mod is now ported to RimWorld Alpha 7. But there are also some small changes and balancing fixes.
Project Armory make weapons from every, era, game and movie. but in first hand with the vanilla RimWorld graphics and sounds. But we also release addon packs with graphical and sound alterations. The Project aim to add as many weapons to RimWorld as possible from old day late medieval weapons to Sci-fi weapons to real world firearms found today. It also aims to make it easy for the user to add and or remove the weapon class the users don't want.
