Armies clash as the world burns. As an inevitable war draws ever closer, you must stand with Chrom and his forces--knights, mages, archers, and more--commanding them against the armies of kingdoms, empires, and the dead themselves. Plan your strategery. Move your troops on the battlefield, then choose their weapon and attack. Using the new Pair Up and Dual systems, support your attacks with the help of nearby allies and watch their skills and relationships grow.
