Underground B45F
地底45層
Underground B45F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 40 energy and sends 10 enemy spawn lines — led by Super Metal Hippoe as the boss — against a 600,000 HP enemy base, and clearing it rewards 2,256 XP. Its enemies carry the Alien and Metal traits, so cats that target them do the most work here.
