Trident Defensive Technologies Series 7 Flechette Cannon has been taken to the next step in evolution with the production of the Mk3 "Negotiator." The ionized flechettes are capable of delivering second- and third-degree burns to organic tissue and cauterizing the wound instantly. Payload delivery is achieved via one of two methods: ionized flechettes launched in a spread pattern directly from the barrel; or via fragmentation grenades that explode on impact, radiating flechettes in all directions. -- Official description

The Flak Cannon is one of the better weapons available. Up close, it can be very dangerous against unarmored foes, and it’s secondary fire is great for distance.

The primary fire consists of several balls of “flechettes” that fly forth from the gun. Like a buckshot shotgun, the flechettes come out packed nice and tight, but spread out the further they travel, making them next to useless against far away opponents. For people who are right next to you, it can kill unarmored enemies with two or three well placed shots. Because of the spread, even an indirect shot as a chance of hitting your opponent.

The alternate mode fires a “grenade” of flechette, which is much better suited to targets farther away. It can damage nearby enemies, but the primary fire mode is better for that. The grenade travels in a short arc, and will explode on contact; doesn’t matter if it’s a wall, floor, vehicle or enemy. If the grenade connects with the enemy directly, they can be killed in one or two shots. Even if the grenade misses, the splash damage will be enough to damage your enemy.

A good use for the Flak Cannon is to fire at enemies who are unaware of you, but also out of reach. If you see an enemy who is inside a turret, fire the grenade at the base of the gunner, damaging both the turret and player. Chances are the player will look around for you, but if you are crouched, you can stay out of sight of the turret.
