Each of the pieces of MechaChess is fits a unique role, with different capabilities, strengths and weaknesses. The robots (and mecha) are specially developed to serve these roles: The King holds the pilot and must be defended; the Rook is the base defense turret; the Knight the tactical close air support; the Pawn the frontlines soldier. The Queen's power is maximal, only possible because of her transcendent AI , while the Bishop is her Apostle, watching over a long sector of fire, and swiftly taking out opponents that stand in her way.
