Archaeology 501: Analysis
遺物調査Ⅴ分析
Archaeology 501: Analysis is a Battle Cats stage in Empress' Excavation 5. It costs 100 energy and sends 16 enemy spawn lines — led by Crocodylidae Kurocroc as the boss — against a 1,700,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Metal, Floating, Zombie, Behemoth, Angel and Black traits, so cats that target them do the most work here.
