Red Alert 6
警戒Lv.6
Red Alert 6 is a Battle Cats stage in Heralds of The End. It costs 90 energy and sends 10 enemy spawn lines — led by The 4th Angel (Enemy) as the boss — against a 500,000 HP enemy base, and clearing it rewards 12,690 XP. Its enemies carry the Red, Alien, Black, Zombie, Angel and Eva Angel traits, so cats that target them do the most work here.
