Tractor Cannon

"Property of Ishtar Collective. WARNING: Gravity propulsor beam can cause serious injury or even death."

- Weapon description

Tractor Cannon is an Exotic Void Shotgun in Destiny 2. It has the unusual property of having low damage for a shotgun, but incredible knockback.

Gameplay
Tractor Cannon fires Void blasts that knock targets back and stun them. This allows the wielder to either shove enemies into walls, causing extra damage, or off a ledge to kill them outright. Kills with this weapon will trigger its The Scientific Method perk, which will increase movement speed and weapon handling for a short time; the buff's duration is refreshed if the user nets another kill. Its Repulsor Force perk also means enemies will be suppressed and cannot use their abilities for a while, and be be 30% more vulnerable to incoming damage.

Perks

 * Repulsor Force: This weapon emits a powerful impulse that pushes enemies away, suppresses their abilities, and makes them more vulnerable to all incoming damage.
 * Extended Barrel: Weighty barrel extension. Increases range. Decreases handling speed. Moderately controls recoil.
 * Particle Repeater: Improves stability. Increases stability.
 * The Scientific Method: Damaging an opponent temporarily increases speed and handling.
 * Composite Stock: This weapon has a versatile dual-purpose stock. Slightly increases stability. Slightly increases handling speed.

Catalyst
The catalyst for Tractor Cannon has a chance to drop from any non-Guardian enemies in the Sol System once the weapon has been acquired.

The catalyst, once completed, will grant an additional perk:
 * Deeper Pockets: Increased ammo reserves.

Lore
'''PROPERTY OF ISHTAR COLLECTIVE. WARNING: GRAVITY PROPULSOR BEAM CAN CAUSE SERIOUS INJURY OR EVEN DEATH.'''

Chioma Esi met Maya in their undergraduate gym. They got into an argument about deadlifting: was it necessary, was it practical, why was Chioma making so much noise? Maya Sundaresh just couldn't stand the notion that some things were done for their own sake, not because they had any use. Decades later they joined the Ishtar Collective on Venus to study the enigmatic ruins unearthed by the Traveler's terraforming. The first time it happened—Vex code leaping across an airgap, surfing the quantum vacuum from simulation to reality, infecting a utility frame—Chioma pulled an alarm while Maya tried to grab the precious frame with a cargo-grade gravity grapple. She couldn't lift the grapple. Chioma grabbed it, pinned the frame to the wall, and won the argument.

Trivia

 * The design aesthetic of this weapon is reminiscent of the Hunter's assault cannon in the Halo series.
 * The weapon was originally property of the Ishtar Collective, to lift and move heavy objects. The way Guardians utilize it is much more simple, as the Cannon's only apparent ability is to push enemies away with brutal force. This might hint against that someone reprogrammed it, perhaps to survive after the Collapse, or that it became damaged by unknown means.
 * Guardians may also simply be neglecting to use the weapon's lifting capability.
