Mercury
水星
Mercury is a Battle Cats stage in Cats of the Cosmos Ch. 2 (Zombie). It costs 64 energy and sends 9 enemy spawn lines against a 216,000 HP enemy base, and clearing it rewards 2,500 XP. Its enemies carry the Zombie, Alien, Floating and Behemoth traits, so cats that target them do the most work here.
