2015 Debut
2015年デビュー
2015 Debut is a Battle Cats stage in Pt. 2: Enemy Maneuvers. It costs 120 energy and sends 11 enemy spawn lines — led by Count Owlbrow as the boss — against a 150,000 HP enemy base, and clearing it rewards 10,716 XP. Its enemies carry the Alien, Floating and Red traits, so cats that target them do the most work here.
