BattleMage TD is a 1on1, multi-player tower defense battle. Players attack their base with various units, at the same time trying to defend their own base from the opposing players attacks. Players can defend their bases with a variety of towers and spells, and attack with spells and units. In BattleMage TD, the goal is to destroy the opposing castle. The only way to damage a castle is with attacking units. Once a castle has been destroyed the game ends. Players earn experience points as they play, and can level up and earn BattleBucks to spend in the shop.
