Cats of the Cosmos Ch. 3 (Zombie Filibuster) — Stage 1
フィリバスター襲来（ゾンビ）
Cats of the Cosmos Ch. 3 (Zombie Filibuster) — Stage 1 is a Battle Cats stage in Cats of the Cosmos Ch. 3 (Zombie Filibuster). It costs 150 energy and sends 17 enemy spawn lines — led by Filibuster Obstructa as the boss — against a 2,500,000 HP enemy base, and clearing it rewards 1,000 XP. Its enemies carry the Alien, Zombie, Angel and Floating traits, so cats that target them do the most work here.
