The M-25 Hornet is a submachine gun in Mass Effect 3 and a pistol in Mass Effect: Andromeda.

Mass Effect 3[]


The Hornet is a long-range submachine gun created by Cerberus. It is standard equipment for Cerberus troops, who are trained to handle the recoil from the gun's three-round bursts. Cerberus designed the Hornet to conserve ammunition and provide cover-fire during prolonged conflicts.



The M-25 Hornet can be found during the mission Priority: The Citadel II, on the body of a C-Sec officer; after exiting the elevator, proceed down the hall to the second flickering light. It is also purchasable from Batarian State Arms after the preceding mission, Priority: Tuchanka.


Weapons are randomly rewarded through purchases of item packs. The M-25 Hornet is classified as rare.

Player Notes[]

  • The Hornet has three key strengths. First is its outstanding damage rate, which comes from a combination of high damage per shot, very high rate of fire, short burst refire time, and very quick reload. The only other SMG which can exceed the Hornet's damage rate is the N7 Hurricane. Second is the Hornet's ability to be effective at any range, which depends on the player's ability to handle recoil. Third is the fact that, like any SMG, the Hornet can have very low weight with SMG Ultralight Materials, which results in one of the most potent weapons being practically weightless.
  • Following the in-game description of a "long-range" gun which needs specifically trained people to handle it, the Hornet is extremely accurate, but has a very high amount of recoil.
  • When on the run and at close range, you are far better off firing the Hornet from the hip than aiming down the sights; the recoil will be far less noticeable.
  • With the SMG Ultralight Materials mod and a SMG High Caliber Barrel or SMG High-Velocity Barrel, this SMG can be an excellent primary weapon for a power-focused class.

  • When fired from the hip, the Hornet's recoil is easy to compensate for by lowering your aim while pulling the trigger. Coupled with the extreme accuracy of the gun, it allows for precise fire while moving, making the Hornet very effective for run-and-gun tactics.
  • Similar to other high-recoil weapons like the M-15 Vindicator, the Hornet's muzzle climb is half again as bad when zoomed in. Taking cover significantly reduces the recoil, allowing you to take advantage of Hornet's accuracy for long-range fire without as much hindrance. The recoil is still noticeable and needs to be compensated for, if you wish to land all three bullets precisely at the same place.
  • The Hornet has a lower clip capacity than other SMGs, which makes precision even more important. However, this is offset by a very quick reload speed. Adding an SMG Heat Sink or an SMG Magazine Upgrade allows for nearly continuous fire.
  • Alongside the N7 Hurricane, the Hornet is one of the few SMGs that are moderately effective against armor due to high damage per individual shot. Coupling the high damage rate with the fact that most armored targets are easy to hit, the Hornet is a decently effective anti-armor weapon.
  • The SMG Recoil System mod added in the Mass Effect 3: Earth DLC is a godsend to players who enjoy the Hornet. Even low levels of the mod have a very noticeable effect on the gun's recoil - rapid-firing bursts from cover is gratifyingly precise and firing aimed bursts while on the move becomes progressively easier as higher levels of the SMG Recoil System are obtained. With the SMG Recoil System equipped the Hornet becomes a superb all-purpose weapon that performs well in most any situation the player finds themself in. However, the only weakness to this is that the SMG Ultralight Materials mod cannot be equipped at the same time, leaving power based classes at a disadvantage.

Mass Effect: Andromeda[]


The M-25 Hornet is a heavy submachine gun that fires three-round bursts. Originally created in the Milky Way by the paramilitary group Cerberus. The Andromeda Initiative's Hornet stockpile was seized from a Cerberus base by the Systems Alliance, then bought by the Initiative at a semi-legal auction.


The weapon's damage displayed is per round, as reflected in the Mass Effect: Andromeda APEX HQ app.

The Hornet obtained multiple changes mostly to damage, though in multiplayer as of the very last update it also saw improvements to reload times, burst fire times, and mag size.


  • Like its Mass Effect 3 incarnation, the Hornet boasts one of the highest damage-per-second ratings in the game due to its incredible firing rate, limited only by its burst firing mode and high recoil. This makes it ideal for the Beam Emitter augmentation, which converts the weapon to full auto and removes recoil entirely at the cost of a -80% Weapon Damage penalty. The Hornet suffers less from this penalty than most other weapons because the Beam Emitter factors the original weapon's rate of fire into the resulting weapon's damage formula, and doesn't penalize it unlike per-shot damage. The result is a weapon that deals high damage with pinpoint accuracy and is light enough to carry alongside other weapons without affecting Ryder's power recharge rate.

  • The Hornet is ideal for classes watching their loadout weights, as even at its heaviest it only takes up 15 weight units out of the default 30 units for all classes. This essentially means the Hornet can function as a main weapon while another can be taken as a sidearm.
