Cats of the Cosmos Ch. 3 (Zombie) — Stage 18
シリウス
Cats of the Cosmos Ch. 3 (Zombie) — Stage 18 is a Battle Cats stage in Cats of the Cosmos Ch. 3 (Zombie). It costs 88 energy and sends 8 enemy spawn lines — led by Lord Gravey as the boss — against a 367,500 HP enemy base, and clearing it rewards 6,100 XP. Its enemies carry the Alien and Zombie traits, so cats that target them do the most work here.
