Fire Emblem Heroes has a new game mode and it's a rhythm, dungeon game called Tap Battle.
Tap Battle is a two-week event where players can jump into the Illusory Dungeon and battle against enemies in time with the beat. By tapping the lane which has an enemy in it at the right movement, players will defeat them and continue to fight throughout the whole song. Nintendo have released a video which you can view above to see the game mode in action.
Fire Emblem Heroes is currently available for both iOS and Android.
