The M-9 Tempest is a submachine gun in Mass Effect 2 and Mass Effect 3.

Mass Effect 2[edit | edit source]

Description[edit | edit source]

This submachine gun fires in long deadly bursts. Very effective against shields and biotic barriers. Inaccurate at long range. Weak against armor. Upgrades the Shuriken Machine Pistol.

The commonality of kinetic barriers has led to increased demand for rapid-fire weapons like the Tempest. Produced by Elanus Risk Control Services for the Eclipse mercenary band, the Tempest is an expensive but deadly addition to anyone’s personal arsenal.

Acquisition[edit | edit source]

The Tempest is acquired from a dead quarian during Tali's recruitment mission. Make sure to pick it up before you answer the quarian radio. If you ever miss that one for whatever reason, you may have your second chance to pick up the Tempest in the room blocked by a pillar (which you have to blow up), where you can talk to Tali by radio.

Squad Use[edit | edit source]

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

Player Notes[edit | edit source]

  • Its high capacity magazine, spare ammo and reasonable damage make it an excellent anti-shield/barrier or suppressive weapon.
  • This weapon only fires in automatic mode or five-round burst fire mode. It is impossible to fire a single round. This five-round burst will happen even if fewer than five rounds remain in the magazine when fired.
  • While initial accuracy is good, bullet spread increases very rapidly when using automatic fire making the Tempest one of the least accurate weapons during automatic fire. Recoil is substantial as well, requiring significant compensation. Good accuracy can be maintained by firing in five-round bursts with pauses between bursts, though of course this will reduce damage output.
  • Tempest vs M-12 Locust: At short range, the Tempest will do slightly more damage to barriers, health, and shields and slightly less against armor. However, due to much lower bullet spread and recoil on automatic fire, the Locust outperforms the Tempest at medium and long range.
  • Squadmates do not suffer from accuracy-related issues, and they also tend to fire the Tempest in longer bursts than the Locust, making the Tempest the superior SMG choice for them.

Mass Effect 3[edit | edit source]

Description[edit | edit source]

Produced by Elanus Risk Control Services for the Eclipse mercenary band, the Tempest is an expensive but deadly addition to anyone's personal arsenal. This fully automatic submachine gun is punishing up close, but becomes less accurate at long range.

Acquisition[edit | edit source]


The M-9 Tempest can be found during the mission Tuchanka: Turian Platoon, next to the turian bodies after killing the first group of husks. It is purchasable from Kassa Fabrication post-mission if it was missed.


Weapons are randomly rewarded through purchases of item packs. The M-9 Tempest is categorized as uncommon.

Player Notes[edit | edit source]

  • The Tempest is a submachine gun that has several strengths. The Tempest has a moderately fast rate of fire, a good clip capacity, average accuracy, and moderate damage for its class. Its rate of fire means it is deadly at close range. It does more damage than the M-12 Locust, and the M-4 Shuriken, though the Shuriken inflicts damage faster.
  • The main drawback with the Tempest is its heavy recoil, even when used in cover. Burst-firing is highly recommended at medium to long range combat; otherwise you will waste a lot of shots. Another drawback is it reloads slower than the other submachine guns, which can prove costly if enemies start drawing closer upon reloading.
    • The recoil, however, can be mitigated by holding the gun towards a downward direction while pressing the trigger. To manage this easier, fire from cover or have an SMG Scope attached.
  • Marksman further increases the already quick rate of fire of the Tempest, at the cost of even heavier recoil. With this power, this beats the Geth Pulse Rifle in terms of rate of fire and damage.
  • Because the Tempest is fairly light, though slightly heavier than the Shuriken, it doesn't really benefit from the SMG Ultralight Materials mod, though it helps reduce weight when using a second weapon with the Tempest. The SMG Scope is also fairly weak since the Tempest still recoils heavily and affects your aiming. The space would be better occupied by a SMG High Caliber Barrel, in order to up the Damage Per Shot (DPS) by a bit.

  • A Tempest attached with an SMG Magazine Upgrade and an SMG Heat Sink provides the second longest suppressive fire (without the need to reload), only beaten by the Geth Plasma SMG. Upgrading the level of the mods mentioned further increases the time it can be fired before the magazine empties. Upgrading the Tempest also increases its damage. Although the Geth Plasma SMG fires faster and has a bigger magazine, it needs to spin up to reach its peak rate of fire, thus limiting its flexibility.
  • The recoil can be drastically reduced (but not eliminated) by playing as a Cabal Vanguard, Turian Sentinel, or a Turian Soldier and evolving Turian Veteran to increase stability. This makes the Tempest far better than the M-12 Locust or the M-4 Shuriken.
  • A Turian Soldier is particularly effective with the Tempest, able to utilise its Marksman power to shred through enemies even on Gold.
  • When equipped with a SMG Recoil System, the Tempest becomes a fabulous all-round weapon, and is decently effective at long range. When equipped with a SMG High-Velocity Barrel, it becomes a veritable powerhouse against targets such as Brutes, Banshees, and Atlases. This combination is perfect for power-oriented classes, since even without the SMG Ultralight Materials mod (which cannot be equipped at the same time as the SMG Recoil System) it is quite light. Essentially, the SMG Recoil System and SMG High-Velocity Barrel can turn the Tempest into a weapon that is noticeably superior to most of the lighter assault rifles (such as the M-8 Avenger, Geth Pulse Rifle, or Phaeston).
  • A Turian Soldier utilizing Marksman with its Accuracy maxed from Turian Veteran, or an N7 Destroyer Soldier with Devastator Mode maxed for Accuracy bonuses can turn the Tempest into a very effective long range weapon. Combine this with a SMG Recoil System and you have a weapon that fires with pinpoint accuracy, allowing for constant headshots.

Trivia[edit | edit source]

  • Despite the muzzle flash coming from the bottom barrel, the High Caliber Barrel mod appears attached to the top one.
  • In Mass Effect: Andromeda, the name of M-9 Tempest has changed to "Charger" to avoid clashing with the name of the Pathfinder's spaceship Tempest.
