Virus Smugglers
感染者密航
Virus Smugglers is a Battle Cats stage in Quarantine Isles. It costs 110 energy and sends 12 enemy spawn lines — led by The Face as the boss — against a 500,000 HP enemy base, and clearing it rewards 88,407 XP. Its enemies carry the Floating and Zombie traits, so cats that target them do the most work here.
