LOST (Insane)
ロスト 超激ムズ
LOST (Insane) is a Battle Cats stage in 消滅都市 ～第３章～(旧). It costs 100 energy and sends 15 enemy spawn lines — led by Yuki (Enemy) as the boss — against a 360,000 HP enemy base, and clearing it rewards 14,100 XP. Its enemies carry the Angel, Black and Floating traits, so cats that target them do the most work here.
