It's a hand mortar based on a Greymourn Mortar from Mutant Chronicles: WarZone game. I took the basic idea of rotary loaded hand mortar and redesigned it in my way. I wanted it to look a little bit Fallout like style. Rockets are mounted on a revolving drum then are loaded inside with a small carriage. To minimize recoil mortar butt is equiped with pistons.
