PPSh-41 Ember PPSh-41SMG 62 Underbarrel launcher that fires a rapid burst of pyrotechnic projectiles which keep burning briefly for area control.

Rezi 12 Enforcer Rezi 12Shotgun 60 Enables pump-action cycling and adds a side-saddle of hot-loaded explosive slugs. Nothing
Warlord Lumen WarlordShotgun 60 Strobe that triggers as soon as you aim down sights and impairs enemy vision. It must recharge between uses.
