N77 Nebula
N77星雲
N77 Nebula is a Battle Cats stage in Cats of the Cosmos Ch. 3 (Zombie). It costs 97 energy and sends 13 enemy spawn lines against a 539,000 HP enemy base, and clearing it rewards 14,200 XP. Its enemies carry the Metal, Zombie, Relic, Behemoth and Alien traits, so cats that target them do the most work here.
