M-22 Eviscerator

The M-22 Eviscerator Shotgun is a longer-range shotgun with armor-piercing loads, available alongside the Cerberus Assault Armor DLC.

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-22 is not distributed to militaries.

Acquisition
Cerberus Network DLC.

Player Notes

 * The M-22 renders the M-23 Katana obsolete from the beginning of the game, even with its lower thermal clip capacity. The only comparable weapon is the M-300 Claymore which has slightly higher damage but the M-22 still has better ranged damage and more ammo capacity. However the M-22's one-shot kills are rare on Insanity difficulty, making the M-300 Claymore a better weapon for hit-and-run tactics, while sacrificing any crowd control.
 * The Eviscerator gains 2 ammo per a thermal clip dropped by an enemy and 4 ammo per a thermal clip picked up from a set location on the map. The ammo per thermal clip counts double once the ammo upgrade has been bought.
 * As its in-game description explains, the Eviscerator uses default weapon range values instead of the shotgun-specific values. This means its damage modifier over distance is the same as an assault rifles'. This does not improve the shotgun's accuracy at range, only the damage it can inflict.
 * The in-game description mistakenly refers to this gun as the M-22a Eviscerator. However, its name only changes to this after buying one shotgun damage upgrade.
