All newsPlayers around this dateRead on Steam

An unprecedented anomaly is about to sweep through Gensokyo!

Get ready for Mutation Mode, a brand-new co-op challenge experience. Each Mutation contains two unique events—offering distinct strategies, shifting battlefield conditions, support units on both sides, and unpredictable mutated bosses!

Mutation #1: Red Packet Frenzy In a festive twist, Reimu is distributing spiritual “Red Packets” across the battlefield. But beware—enemies and bosses are trying to twist this celebration to their advantage. Is it a blessing or a trap? Only teamwork can lead you to victory!

This Mutation includes two events. Now available:

• Event 1: Trial of Greed Collect scattered Red Packets infused with spiritual power, avoid enemy interference and traps, and make good use of support units to gain the upper hand!

More Mutation Modes are under development—each one packed with new map mechanics and surprise boss encounters. Stay tuned for the full release of Mutation Mode, and push your strategy to the limit!
