Cats of the Cosmos Ch. 2 — Stage 23
デネブ
Cats of the Cosmos Ch. 2 — Stage 23 is a Battle Cats stage in Cats of the Cosmos Ch. 2. It costs 85 energy and sends 8 enemy spawn lines — led by Galactic Overseer Nyandam as the boss — against a 440,000 HP enemy base, and clearing it rewards 7,600 XP. Its enemies carry the Alien and Floating traits, so cats that target them do the most work here.
