レジャー施設なら草衙駅
高雄メトロ レッドライン — Stage 3 is a Battle Cats stage in 高雄メトロ レッドライン. It costs 120 energy and sends 9 enemy spawn lines — led by Nana & Doge as the boss — against a 45,000 HP enemy base, and clearing it rewards 62,040 XP. Its enemies carry the Metal and Black traits, so cats that target them do the most work here.
