Impact Site (Insane)
隕石墜落跡地 超激ムズ
Impact Site (Insane) is a Battle Cats stage in Cavern of Comets. It costs 200 energy and sends 11 enemy spawn lines — led by J.K Bun Bun as the boss — against a 400,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Alien, Red and Floating traits, so cats that target them do the most work here.
