Earth
地球
Earth is a Battle Cats stage in Cats of the Cosmos Ch. 3 (Zombie). It costs 70 energy and sends 6 enemy spawn lines — led by Mesocosmocyclone as the boss — against a 168,000 HP enemy base, and clearing it rewards 1,000 XP. Its enemies carry the Zombie and Alien traits, so cats that target them do the most work here.
