Special Stages 400: Stage 4
蒼色に染まる戦場
Special Stages 400: Stage 4 is a Battle Cats stage in 蒼船来航. It costs 150 energy and sends 9 enemy spawn lines — led by Commander Ostromeda as the boss — against a 700,000 HP enemy base, and clearing it rewards 13,395 XP. Its enemies carry the Alien trait, so cats that target it do the most work here.
