Cosmic Frontier

蒼き本能の秘境

Cosmic Frontier is a Battle Cats stage in Island of Hidden Treasure. It costs 300 energy and sends 8 enemy spawn lines — led by Bun Bun Symbiote as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 26,790 XP. Its enemies carry the Alien and Floating traits, so cats that target them do the most work here.
