Otherworld Colosseum · Stage 3
Round 3
Round 3 is a Battle Cats stage in Otherworld Colosseum 23. It costs 200 energy and sends 11 enemy spawn lines — led by Sir Metal Seal as the boss — against a 2,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Metal and Black traits, so cats that target them do the most work here.
