Fights in Battle Defenders are divided into offensive and defensive rounds. As a defender, players are tasked with setting up units and barriers to repel the invading team. Successfully keeping the opposing force at bay nets players with coins for every enemy defeated and ensures they’ll survive long enough to counter-attack. During the offensive round, players are given the opportunity to swiftly devise an attack plan and send a hand-picked group of units to the front lines. As the group navigates the fiendish gauntlet the opponent has built, players are rewarded for the damage they do. If they get enough units through to the enemy flag, they win the fight!
