Control over the hovertank and destroy enemy base.
The player is part of a team, and can help that team win in many different ways. Without going into excruciating detail, the players can help build new bases, help place strategic elements that allow spaceships to maneuver, help your frontline tanks by going in with a medic unit and repairing their damage on the battlefield, help the team by rushing enemy bases all alone, or be part of a large group of frontline tanks that battle it out over the territory at hand.
