Semi-Auto Shotgun
Weapon · WeaponShotgun3★Semi-Auto Shotgun is an early weapon: 33rd of 40 by attack, so treat it as a stepping stone, at 253 against the 1,400 of Prototype Shotgun.

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.
