Underground B43F

地底43層

Underground B43F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 40 energy and sends 6 enemy spawn lines — led by Calamary as the boss — against a 600,000 HP enemy base, and clearing it rewards 2,256 XP. Its enemies carry the Floating and Alien traits, so cats that target them do the most work here.
