Mutation Lv.MAX
突然変異Lv.MAX
Mutation Lv.MAX is a Battle Cats stage in Resident Undead. It costs 180 energy and sends 15 enemy spawn lines — led by Zamelle as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 25,380 XP. Its enemies carry the Alien and Zombie traits, so cats that target them do the most work here.
