Underground B29F

地底29層

Underground B29F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 30 energy and sends 6 enemy spawn lines — led by Professor A. as the boss — against a 600,000 HP enemy base, and clearing it rewards 1,692 XP. Its enemies carry the Red and Colossus traits, so cats that target them do the most work here.
