A Heavy Burst Cannon is a larger variant of the standard Tau Burst Cannon that possesses six large barrels with extended lengths. It is capable of a ferocious rate of fire that can mow down hordes of enemies with ease. Developed during the Tau Empire's Third Sphere Expansion, the Heavy Burst Cannon is only mounted as a primary arm weapon on the experimental XV104 Riptide Battlesuit. A Heavy Burst Cannon can also draw upon the XV104’s Dark Matter Nova Reactor to nova-charge itself, making possible a devastating hail of pulse rounds that can crack even the toughest of armours with ease.
