Revolver

The Revolver is the first gun you can create in Barren. It is normally a three shot kill and uses the Heavy Bullet type. It deals 21 damage, with 8 bleed damage in a total of 29 damage without Bandages. Because it is the one of the first guns in the game you can create, it doesn't take that much to craft itself.

It is also very common in Barrels, but easily scrapped as it is very 'underrated'. Some people still use it however, and say it is one of their favorite guns.
