"A heavy driver that hurls a container that detonates at a set distance and sprays the area with hyper-velocity shrapnel. Very good at damaging tight groups of small enemy ships."
Bursters unlock the weapon system of the same name, Bursters(weapon) for use in any large weapon mount. This node is the first in the Ballistics Weapons tree which unlocks a weapon more useful for crowd control than damage dealing, though Bursters can do passable damage at great ranges if used correctly. The weapon itself is a refinement of the projectile rather than the propulsion system, essentially packing 12 Gauss Cannons into a bullet, taping a timer to it, and shooting them out a much larger Gauss Cannon.
Bursters can cost as much as 90,000 or as little as 30,000 research points, depending on chance.
