Origin 12

The FOSTECH Origin 12 is marketed as the fastest semi-automatic shotgun in the world.

It can easily be confused with an SMG because of it's small size. The size isn't what matters though, cause make no mistake, this small shotgun will take you down within seconds of the first shot. This is the only automatic shotgun in the game, it's damage is average but the firing rate alone makes this gun the best close-range gun. It's just tricky when most of the game is spent at longer ranges, therefore it is an uncommon weapon to be carrying mid/late game.
