M-22 Eviscerator Shotgun
 In-Game Description
The Lieberschaft 2180 shotgun, or "Eviscerator," is of human civilian design and has a unique ammunition generator. Where most modern firearms shave off chips or pellets from an ammunition block, the M-22 shaves off serrated metal edges designed to fly aerodynamically. This dramatically improves its armor-piercing capabilities, and its tight grouping helps wound ballistics at longer ranges than standard shotguns. This design also violates several intergalactic weapons treaties, so the M-22a is not distributed to militaries.
The M-22 Eviscerator is a bonus weapon that the player can download from the Cerberus Network. Initially only the Soldier and Vanguard classes are the able to use Shotguns. During the mission to the Collector Cruiser, all other classes are given the opportunity to specialize in using Shotguns.
