Frag Cannon

The Frag Cannon is the most dangerous and most self-destructive shotgun in Marathon's arsenal — a weapon that fires fragmenting explosive pellets that detonate on contact, dealing massive area-of-effect damage to everything within 3 meters of impact, including the runner who fired it. The Frag Cannon's explosive pellets at close range are among the highest single-pull damage outputs in the game, but the self-damage component makes it essentially lethal to use at point-blank range without Cerberus's Damage Feedback passive or significant health advantage.

Combat Application

The Frag Cannon is the Cerberus Shell's weapon of choice in high-density enemy scenarios. The Iron Bulwark absorbs incoming damage while the Frag Cannon's pellets clear groups, and the Damage Feedback passive means Cerberus is actually benefiting from the incoming fire while dealing AOE damage. Against any other Shell, the Frag Cannon requires minimum 5-meter engagement distance management to avoid self-damage — a challenging constraint in Terminus corridor fights.
