Introduced during the mark 3a phase of Terminator armour development, this weapon is the standard alternative to the heavy flamer as a squad's special weapon.
The weapon was developed after the Horus Heresy as a replacement for the autocannon and Rotor Cannon, which had been a common heavy weapon on Terminator suits until then.
It is a medium-calibre rotary autocannon, with 6 barrels cycled by an electric motor past a single chamber. Its most notable feature is its incredibly high rate of fire, easily eclipsing that of the autocannon it replaced.
