300 Years Probation
懲役300年の執行猶予中
300 Years Probation is a Battle Cats stage in Old Guys About Town. It costs 80 energy and sends 10 enemy spawn lines — led by Mighty Gui Zuli as the boss — against a 75,000 HP enemy base, and clearing it rewards 11,280 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
