高雄MRT オレンジライン — Stage 4

104-03

高雄MRT オレンジライン — Stage 4 is a Battle Cats stage in 高雄MRT オレンジライン. It costs 200 energy and sends 8 enemy spawn lines — led by HAPPI & Maji Cat & Cat (Enemy) as the boss — against a 300,000 HP enemy base, and clearing it rewards 141,000 XP. Its enemies carry the Black trait, so cats that target it do the most work here.
