Fanart of Eviscerator shotguns from Mass Effect, plus a custom version.
The "Hammer of Humanity" was a custom made Eviscerator shotgun made by Cerberus for operative Xander Otarin. Xander had always preferred the Eviscerator, both for it's psychological effects and it's effectiveness against barrier'd enemies at range, but the Hammer was even better: with a longer, heavier caliber barrel and larger thermal clip, he could put out more fire at a time, and with much greater effect. It's modified flechette pattern also wreaked havoc on barriers, and extended heatsink increase rate of fire. The integrated smart pattern-variation system adjusted flechette spread for range, making the weapon just as devastating at any distance. The Hammer was lost during the battle of Thessia, where Xander was forced to leave it behind when the Reapers turned their attention to his mission there. Currently it's believed to be in a police evidence locker on the planet.
