Underground B56F

地底56層

Underground B56F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 40 energy and sends 6 enemy spawn lines — led by Le'noir as the boss — against a 800,000 HP enemy base, and clearing it rewards 2,256 XP. Its enemies carry the Black and Alien traits, so cats that target them do the most work here.
