Alien Ecology
異星生態調査団
Alien Ecology is a Battle Cats stage in Galapa-Goth. It costs 110 energy and sends 10 enemy spawn lines — led by Galactic Overseer Nyandam as the boss — against a 600,000 HP enemy base, and clearing it rewards 88,407 XP. Its enemies carry the Metal and Alien traits, so cats that target them do the most work here.
