Catamin Stages · Stage 1
Flow Like the Stream (Merciless)
河の流れのように 超極ムズ
Flow Like the Stream (Merciless) is a Battle Cats stage in Bottom of the Swamp. It costs Catamin B ×2 and sends 13 enemy spawn lines — led by Kappy Jr. as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Alien and Zombie traits, so cats that target them do the most work here.
