The "Super Shotgun" can be found during the quest "At Hell's Gate" inside the ship "Perseus" just before reaching the cockpit.
It is a unique shotgun whose magazine holds only one round and so must be reloaded after every shot. It does incredible damage at close range, and is designed to reward the player for playing similar to the "up close and personal" playstyle encouraged in the 2016 version of Doom and the follow-up Doom Eternal.
It comes equipped with the following legendary effects: Exterminator, Unstoppable Force, and Rend.
Unstoppable Force is a unique Legendary effect to At Hell's Gate that grants the player immunity to being staggered.
Rend is a unique Legendary effect to At Hell's Gate that restores some of the player's health after they kill an enemy with the weapon.
