Where to Find Semi-Auto Shotgun

Semi-Auto Shotgun is not something you find lying around — you craft it, and the recipe is below.

Schematics That Unlock Semi-Auto Shotgun

Semi-Auto Shotgun is not learned from the Technology tree — you need a schematic for it. One schematic grants the recipe, and they are world loot — chests, boss Pals and the late-game pools — rather than anything you research. Higher-rarity copies of the same schematic raise the quality of what you end up crafting.
