Otherworld Colosseum · Stage 2
Round 2
Round 2 is a Battle Cats stage in Otherworld Colosseum 6. It costs 200 energy and sends 7 enemy spawn lines — led by R.Ost as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Alien and Floating traits, so cats that target them do the most work here.
