Hath blaster

During the seven day war on Messaline the Hath warriors armed themselves with powerful blaster rifles. The rifles were black and seemed to be powered by gas cannisters fixed to the bases of the weapons. They fired a stream of bullets, usually accompanied by a plume of flames. They were similar to the rifles used by the human colonists but had a different exterior design. The rifles were the only weapon seen used by the Hath. (TV: The Doctor's Daughter)
