Tank combat in urban arenas: cities of buildings, ramps, and streets, with up to four factions in each zone. Each faction holds a flag in its base. Capturing an enemy flag and returning it to your own base generates points and improves rank. Movement and aiming run through keyboard or joystick — the mouse is not supported. Player-built maps are available after developer approval, expanding the available terrain. Online play requires a monthly subscription; a free version provides two arenas and one tank for evaluation.
