A Heavy Burst Cannon is a larger variant of the standard T'au Burst Cannon that possesses six large barrels with extended lengths and multiple induction chambers. It is capable of a ferocious rate of fire that can mow down hordes of enemies with ease. It projects plasma rounds further and with greater force than normal Burst Cannons. Even in daylight, these heavy weapons produce a blinding muzzle flash, their barrels a blur of motion as a stream of incandescent fire stretches out before them.
Developed during the T'au Empire's Third Sphere Expansion, the Heavy Burst Cannon is only known to be deployed as a primary arm weapon on the experimental XV104 Riptide Battlesuit. By opening up in-built pulse induction inhibitors, a Heavy Burst Cannon can also draw upon the XV104's Dark Matter Nova Reactor to nova-charge itself, making possible a devastating storm of pulse rounds that can crack even the toughest of armour with ease.
