103-04
高雄MRT レッドライン — Stage 5 is a Battle Cats stage in 高雄MRT レッドライン. It costs 200 energy and sends 9 enemy spawn lines — led by The Face as the boss — against a 250,000 HP enemy base, and clearing it rewards 141,000 XP. Its enemies carry the Floating and Red traits, so cats that target them do the most work here.
