The Wormhole Opens (Deadly)
進撃のワープホール 極ムズ
The Wormhole Opens (Deadly) is a Battle Cats stage in The 2nd Dimension. It costs 200 energy and sends 8 enemy spawn lines — led by Super Cosmic Cyclone as the boss — against a 999,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Alien trait, so cats that target it do the most work here.
