The M-12 Locust is a submachine gun in Mass Effect 2 and Mass Effect 3.

Mass Effect 2[edit | edit source]

Description[edit | edit source]

The Kassa Fabrications Model 12 Locust is a compact submachine gun developed for the Alliance but now favored by gang enforcers and hitmen. Featuring a complex recoil-reducing mechanism and high-grade autotargeting software, the Locust delivers longer-range, more accurate fire than others in its class.

Acquisition[edit | edit source]

The M-12 Locust can be found during Kasumi's loyalty mission in Donovan Hock's vault on the table with the graybox. If the weapon is not picked up, it will be awarded at the end of the mission. Kasumi refers to it as "the gun that killed two presidents."

Note: The Locust is not carried over from one imported game to the next. This is somewhat mitigated by its acquisition mission being available right after Freedom's Progress.

Squad Use[edit | edit source]

This weapon can be used by Miranda, Mordin, Samara/Morinth, Thane, Kasumi, Liara and Dr. Amanda Kenson.

Player Notes[edit | edit source]

  • Although it has lower clip capacity, fire rate and damage output compared to the M-9 Tempest, the Locust makes up for it by being extremely accurate at longer ranges and having virtually no muzzle climb.
  • Like the M-22 Eviscerator shotgun, the Locust sacrifices some of its penetration power against shields and barriers in exchange for extra damage against armor, making it a more balanced general combat weapon than the Tempest.
  • Like the Tempest, the Locust is a definite upgrade over the M-4 Shuriken.
  • Squadmates do more damage with the Tempest than the Locust as they don't suffer any accuracy issues such as recoil and bullet spread.

Mass Effect 3[edit | edit source]

Description[edit | edit source]

The Kassa Fabrications Model-12 Locust is a compact submachine gun developed for the Alliance but now favored by gang enforcers and hit men.

Acquisition[edit | edit source]

Singleplayer

The M-12 Locust can be found during the mission Priority: Horizon, on a table before the terminal showing the proof that Henry Lawson works for the Illusive Man. It is also purchasable from Kassa Fabrication post-mission if it was missed.

Multiplayer

Weapons are randomly rewarded through purchases of item packs. The M-12 Locust is categorized as uncommon.

Player Notes[edit | edit source]

Singleplayer
  • The Locust has an average weight level, moderately-slow rate of fire, very high accuracy, and average clip capacity.
  • The Locust's main strength is its flexibility. It has low recoil, and very high accuracy which allows the Locust to fire full auto even at long range, something no other SMG can do effectively. This means it is very capable of dispatching shielded enemies with little difficulty.
  • As accurate as the Locust is, it has very low rate of fire, resulting in a low damage output, though this is partially remedied by its ability to keep putting headshots on target. As well as this, its slow rate of fire makes it a poor choice for close quarters, where the M-9 Tempest or M-25 Hornet would be far superior due to their faster fire rates.
  • Its excellent accuracy and low recoil make it excel in taking out light and shielded units from afar. This makes it comparable to the Geth Pulse Rifle, although it doesn't have the rifle's fire rate.
  • Though the combination of an SMG Magazine Upgrade and an SMG Heat Sink works to lengthen the time it can fire until the clip empties, it provides little benefit since it has a small magazine. So do the SMG High Caliber Barrel and the SMG Scope; the Locust has low damage and already high accuracy, respectively. The SMG Scope, however, can improve alignment of headshots.
  • Unlike most submachine guns, using the Locust will prompt squadmates to keep their distance from the enemy instead of closing in.

  • The Locust is second best among the other SMGs (defeated by the Geth Plasma SMG for faster rate of fire and better accuracy) for being effective against enemies in medium to even long ranges and consistently hitting enemies in the head, but ultimately is a poor weapon of choice for higher difficulty matches due to the lack of damage output.
  • When the Locust is used by a turian multiplayer character with points invested in the passive class power to increase stability (such as the Cabal Vanguard, Turian Sentinel, or Turian Soldier using Turian Veteran) and in conjunction with a SMG Scope, recoil is almost negligible and otherwise very predictable. The remaining recoil is easily countered allowing for rapid easy headshots at medium range.
  • Following an update on Sept 18, the Locust now has a 3x headshot multiplier instead of the usual 2.5x, and its damage output overall has also been increased.

Trivia[edit | edit source]

  • The Locust makes considerably less noise and has a much smaller muzzle flash than other SMGs. This may be because it is meant to be a suppressed weapon, which fits in with its in-game description as a weapon favored by hitmen and assassins.
  • Despite a vertical fore-grip being integrated into the design of the Locust, there is no animation for any character in Mass Effect 2 or Mass Effect 3 utilizing this specific feature of the weapon. Because of this, any character wielding the Locust grips it as if he or she is holding a heavy pistol or any of the other submachine guns.
