When the Battle for KSP began Matt-D2105 was stationed on the ground and did work similar to Peri, except he didn't move over so great an area and generally took on larger targets. His moment came when a Wraith moved in to his street, supported by several Prowlers. Matt ambushed them, killing the gunners with a series of well thrown plasma grenades and several rounds of buckshot. The Wraith fired at Matt, who ducked out of the way and boarded the tank. Ripping the hatch open, Matt shoved a plasma grenade inside and leapt away, leaving the snarling Brute to his fate.
