The M-6 Carnifex is a heavy pistol in Mass Effect 2, Mass Effect 3, and a pistol in Mass Effect: Andromeda.

Mass Effect 2


Highly accurate and lethal sidearm. Effective against armor; weak against shields and biotic barriers. Upgrades the Predator heavy pistol.

The Carnifex is a favored sidearm of mercenary leaders and Eclipse mercenary tech specialists. An expensive but powerful weapon. Its marketing materials feature a charging krogan with the slogan "Don't you wish Carnifex was at your side?"


The M-6 can be obtained while recruiting Mordin Solus on Omega. Mordin gives it to Shepard when the Commander arrives at the med clinic and mentions that it was recovered from a dead Blue Suns mercenary.

Squad Use

This weapon can be used by Jack, Jacob, Miranda, Mordin, Tali, Kasumi, Liara and Wilson.

Player Notes

  • Although dealing increased damage over the M-3 Predator, the M-6 has:
    • A slower firing rate;
    • Much more recoil and a slower recovery rate; and
    • Less magazine and spare ammo capacity.
  • Using Cryo Ammo may help to offset the Carnifex's very low ammo supply, as frozen enemies take twice as much damage and therefore fewer shots to kill.
  • The Carnifex is in general the best heavy pistol option for squadmates as they deal the most damage with it compared to the alternative options, and they are unaffected by the weapon's recoil or low spare ammo count.

Mass Effect 3


A highly accurate and lethal pistol. The Carnifex is a favored sidearm of mercenary leaders and Eclipse mercenary tech specialists. An expensive but powerful weapon, its marketing materials feature a charging krogan with the slogan "Don't you wish Carnifex was at your side?"



The M-6 Carnifex is found during the mission Arrae: Ex-Cerberus Scientists, on a pipe in the tunnel immediately after leaving the scientists. It is also purchasable from Kassa Fabrication post-mission if it was missed.


Weapons are randomly rewarded through purchases of item packs. The M-6 Carnifex is categorized as rare.

Player Notes

  • With appropriate mods, the Carnifex can be utilized to fill the role of a long-range sniping weapon. The weapon's considerable damage, when coupled with a Pistol Scope, can provide a lightweight solution to handling enemies at range. On Normal difficulty, the Carnifex is easily capable of dropping enemies with a few headshots.
  • The Carnifex easily does more damage per shot than some semi-automatic sniper rifles such as the M-97 Viper or M-13 Raptor. Its lower weight makes it a good substitute for long-range fighting with classes that have low weight capacity bonuses.

  • The Carnifex is a powerful weapon for its category. On Bronze difficulty, it can kill any unprotected enemy with a headshot. Shielded organic enemies require two or three hits. With multiple weapon damage upgrades, it can retain the same stats on higher difficulties, though one more shot may be required for tougher enemies. On Gold, only through an Infiltrator's Tactical Cloak damage bonus can players one shot Assault Troopers or Guardians. Otherwise, it requires at least two shots to the head to kill unshielded enemies, and at least 3 to kill shielded enemies.
  • Combining the Carnifex with Stasis makes for a potent combination. With sufficient power duration bonuses, Stasis can hold an enemy in place long enough to put as many headshots as necessary to kill the intended target. This is particularly useful against Phantoms, as they are very dangerous at close range but only require a couple of headshots to kill.
  • The Carnifex is a good weapon for the Vanguard class to use, as its relatively low weight and high accuracy and damage allows the Vanguard's powers to recharge quickly as well as having the bonus of a high-damage weapon.
  • The Carnifex is very useful when equipped with the Pistol Piercing Mod as it allows for much easier performance of headshots on Guardians, which is an important consideration on higher difficulties. This mod also helps speed up killing enemies with massive amounts of base armor (such as Atlases) and allows you to shoot enemies out of thin cover simply by shooting their cover.
  • Equipping the Pistol Scope is inadvisable, as the gun is pin-point accurate in cover, and extremely accurate out of cover, even at range. Only at 10-15 meters out and further does accuracy become a mild issue when shooting out of cover.
  • Without Tactical Cloak, one can kill a Geth Rocket Trooper with two headshots, even on Gold difficulty. This is even true with classes such as the Salarian Engineer, who has a measly 5% weapon damage bonus by rank 2 of Salarian Operative.
  • Used in tandem with Overload or Energy Drain, you can strip the shields of most infantry in one go, then with one well-placed headshot, subsequently kill weaker infantry.
  • Adrenaline Rush is an effective means of increasing damage for the Carnifex. Since it lasts 5-6.8 seconds and does 50-70% extra damage, one can fire off at least 1 entire clip of ammunition before losing this bonus, compared to 2 or 3 shots from Tactical Cloak. It may not affect how many shots are needed to kill shielded enemies, however. Consider teaming up with somebody with Overload to pick enemies off.
  • In an update, the Carnifex had its weight increased from 50 to 70, potentially making it less viable for power-intensive classes.

Mass Effect: Andromeda


A heavy semi-automatic pistol, the powerful Carnifex was the preferred choice of Milky Way mercenaries. An expensive weapon, its marketing materials featured a charging krogan alongside the tagline "Don't you wish Carnifex was at your side?"


Post-launch, the Carnifex gained improvements to damage, clip size, and max ammo. Damage in particular was adjusted thrice.

  • Carnifex means "butcher" in Latin - literally, "a maker of meat". Due to the tendency to employ butchers as public executioners, the word carnifex shifted from its original meaning and came to mean both a butcher and an executioner.
  • The appearance is based on the alternate pistol in Mass Effect.
  • The pistol has "Magnus" (Latin for "great") written on its side. This is a possible reference to highly powerful 'magnum' cartridges, which are enlarged versions of other existing cartridges, and possess immense stopping power.
  • The M-77 Paladin and M-11 Suppressor are variants of the Carnifex.
  • During Mass Effect 3, in the course of unsuccessfully trying to persuade Mordin Solus to sabotage the genophage cure, the Commander threatens him with a Carnifex, the same weapon Mordin offered Shepard as a sign of goodwill in Mass Effect 2. This happens regardless of which pistol the Commander has equipped at the time.
  • The gun has a dial on the side with "Auto" written next to it, suggesting that the weapon can be fired full auto. This can be seen when modding in Mass Effect 3.
  • Mass Effect: Andromeda doesn't use the M-6 designation that prior Mass Effect games use for this pistol.
