Cats of the Cosmos Ch. 1 — Stage 15

卵星雲

Cats of the Cosmos Ch. 1 — Stage 15 is a Battle Cats stage in Cats of the Cosmos Ch. 1. It costs 65 energy and sends 6 enemy spawn lines — led by Ursamajor as the boss — against a 145,000 HP enemy base, and clearing it rewards 5,200 XP. Its enemies carry the Alien trait, so cats that target it do the most work here.
