Red Alert 20

警戒Lv.20

Red Alert 20 is a Battle Cats stage in Heralds of The End. It costs 150 energy and sends 8 enemy spawn lines — led by The 9th Angel (Enemy) as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 21,150 XP. Its enemies carry the Angel, Eva Angel and Red traits, so cats that target them do the most work here.
