Synthol Swamp
欺きのムキムキ
Synthol Swamp is a Battle Cats stage in Muscle Empire. It costs 200 energy and sends 6 enemy spawn lines — led by Le'Prude as the boss — against a 1,800,000 HP enemy base, and clearing it rewards 482,220 XP. Its enemies carry the Red and Black traits, so cats that target them do the most work here.
