U.F.O.軍団 強襲！ — Stage 15
⑮沈みゆくかやく
U.F.O.軍団 強襲！ — Stage 15 is a Battle Cats stage in U.F.O.軍団 強襲！. It costs 100 energy and sends 4 enemy spawn lines — led by Yakisoba Face as the boss — against a 360,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
