Otherworld Colosseum · Stage 2
Round 2
Round 2 is a Battle Cats stage in Otherworld Colosseum 13. It costs 200 energy and sends 10 enemy spawn lines — led by Sir Metal Seal as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Metal and Zombie traits, so cats that target them do the most work here.
