The report of the Gauss cannon turret was deafening, sniping a barrel-rolling banshee in mid-roll. Alastor watched it slammed into a clump of promethean Crawlers, splattering ten of them as well as a promethean knight that teleported into the path of the debris. Another shot hulled a promethean watcher that dove in to revive the knight. A third took another banshee which had started a strafing run. Seeing the plasma mortar of a covenant wraith arcing in he spun the Gauss turret sideways and crouched, punching the bed of the warthog. A purple dome of hexagonal energy plates expanded from his armor, covering a ten yard area  around the mobile vehicle.<br/><br/>"That would have been a direct hit," Lunamaria reported as the mortar detonated against the dome shield he'd produced, "Nice timing, but we better dump the vehicle for now. Not enough room to maneuver with it in this area, plus I think you got a "Killionare" off those Crawlers."
