The Blackstorm's relatively high ammo usage, slow moving shot, and delayed damage means it should generally be used only in situations where lots of enemies are packed into a restricted area where they can't escape from the blast such as a corridor or small room.The Blackstorm does not cause any type of friendly fire to Shepard or Shepard's team regardless of difficulty setting, allowing it to be fired at point-blank range safely.

This makes the Blackstorm one of only two weapons in Mass Effect 2 capable of directly damaging enemies through cover, the other being the Cain.

Enemies killed by the Blackstorm disintegrate leaving no corpse.This makes it fairly useful for tying up foes like Scions for a long time, especially if multiple shots are fired. Unlike the Singularity power, the Blackstorm's vortex duration is fixed and is not reduced by hitting multiple enemies or holding even powerful enemies repeatedly.Unlike the true Singularity, however, enemies pulled into the air and suspended by the Blackstorm's projectile can't be detonated with Warp.Just as with the biotic power Singularity, only unprotected enemies with no shields, barriers, or armor will be pulled into the air by the Blackstorm's projectile, but the vortex will cause slight damage over time to all types of protection and health as well as staggering most enemy types repeatedly.The size of the vortex slightly increases leading up to detonation. If the projectile encounters terrain or directly collides with an enemy it will persist there until detonation which always occurs a set amount of time after firing (about 5 seconds). True to its name, the M-490 Blackstorm shoots out an orange Singularity-like projectile that travels in the direction it was aimed while disrupting enemies it contacts until it implodes dealing massive damage and sending targets within a large area flying.In the Legendary Edition, it can be purchased on Omega at Harrot's Emporium. The M-490 Blackstorm is included in the Terminus Weapon and Armor downloadable content pack. The mass effect field soon destabilizes and returns to normal mass, with explosive results. The rapidly-increasing gravity near the singularity's event horizon rips the objects apart.

This creates a gravitational singularity that draws nearby enemies and objects inward for a short time. The Blackstorm, colloquially called the "black hole gun," encases particles of matter within a high-powered mass-increasing field, elevating them to near-infinite mass.
