Underground B64F

地底64層

Underground B64F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 50 energy and sends 7 enemy spawn lines — led by Sir Metal Seal as the boss — against a 800,000 HP enemy base, and clearing it rewards 2,820 XP. Its enemies carry the Metal trait, so cats that target it do the most work here.
