Cats of the Cosmos Ch. 3 (Filibuster) — Stage 1
フィリバスター襲来
Cats of the Cosmos Ch. 3 (Filibuster) — Stage 1 is a Battle Cats stage in Cats of the Cosmos Ch. 3 (Filibuster). It costs 150 energy and sends 8 enemy spawn lines — led by General GreGory as the boss — against a 2,500,000 HP enemy base, and clearing it rewards 1,000 XP. Its enemies carry the Alien, Floating, Red and Black traits, so cats that target them do the most work here.
