TX-4 mini-series: Armored carrier
Heavy carrier is used for moving larger pieces of machinery, staff, orb samples, etc. A single carrier can transport up to 20 people. Due to the size of a unit, the hangar area is equipped with robotic arms that are used to replace vehicle's energy reactors, recharge oxygen supplies and carry out various maintenance tasks. As a precaution, each carrier has two heavy ray guns and ion missile launchers for offensive actions, though so far such means were not necessary.
Concept prepared for a new e-zine about sci-fi art. When the first issue is out (next month), I'll provide the link.
