The Gun Emporium

The Gun Emporium is the place where you can build and acquire new weapons that can't be found anywhere else in the game. Create new guns by combining regular weapons with Forging Hardware (FH) that you'll acquire by completing Jobs (special missions that are completed in a match), or by spinning the Roulette wheel after completing a match.
