Gameplay is initially focused on base and unit construction. The player starts with a single headquarters building and a few basic units, usually just one construction unit. The subsequent focus of the game then shifts to capturing and holding strategic locations on the battlefield. These control points are captured by infantry squads and provide resources to construct additional units and buildings or unlock certain units in an army's tech tree. Battles are won either by holding a certain number of control points for a period of time or by destroying all of the opposing armies' base structures.
