Megaton Blast (Insane)
グレイト爆進！ 超激ムズ
Megaton Blast (Insane) is a Battle Cats stage in Event All-Stars Grand Jubilee!. It costs 100 energy and sends 11 enemy spawn lines — led by Le'mammoth as the boss — against a 882,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Floating and Red traits, so cats that target them do the most work here.
