Underground B2F

地底2層

Underground B2F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 20 energy and sends 6 enemy spawn lines — led by B.B.Bunny as the boss — against a 200,000 HP enemy base, and clearing it rewards 1,128 XP. Its enemies carry the Red and Floating traits, so cats that target them do the most work here.
