M-9 Tempest

The M-9 Tempest Submachine Gun is a submachine gun from Mass Effect 2.

In-Game Description
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
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
This weapon can be used by Miranda, Mordin, Samara/Morinth, Thane and Kasumi.

Player Notes

 * 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 burst also counts for the last round you fire (in other words, the weapon can fire up to four extra shots after you let go of the trigger.)


 * As with most fully automatic weapons firing in bursts will significantly improve the accuracy of the weapon, although doing so will obviously reduce the weapon's DPS. This is particularly true with the Tempest since the weapon's high recoil coupled with its high rate of fire rapidly deteriorate its accuracy.
 * Tempest vs Locust: DPS-wise, the Tempest possesses better DPS against health, shield and barrier compared to the Locust. Thus this weapon may serve a greater range of use than the Locust. However, the Locust has low recoil and virtually no muzzle climb, allowing longer full-auto firing.


 * Squad mates are very accurate with the Tempest, making this weapon arguably the better SMG choice for them.
