◤Developer Note: Galactic Disaster Season 3 Balance Adjustments◢ (5/8 08:57)

Zero Out All Despair! Hello, This is the Chaos Zero Nightmare Team Season 3 balance adjustments focus on improving Combatants that currently underperform relative to the newly raised overall balance standard, while also ensuring that all characters can shine in the new [Sortie] mode. Even cards with low selection rates can serve meaningful roles depending on your unique deck-building approach as Protos. We’ve taken great care throughout the redesign process to ensure no disadvantages are introduced for Protos. Season 3's balance adjustments are designed primarily to raise the lower performance floor of each character. Accordingly, this update minimizes any large-scale reworks, instead focusing on bringing each Combatant’s core performance up to a consistent baseline. * The adjustments outlined in this balance adjustment notice are subject to change at the time of the actual update. ■ Changes -The "After" values originally released for Magna's Ice Fragment and Ice Fragment's Unique Epip

Zero Out All Despair! Hello. This is theChaos Zero Nightmare Team. Chaos Zero Nightmare is approaching 100 days since its official launch. In this Developer Note, we would like to briefly share some of the most anticipated and frequently asked questions from Protos, along with an overview of the Season 2 update.

◤Developer Note: 2026 Roadmap Showcase◢

Zero Out All Despair! Hello. This is theChaos Zero Nightmare Team. Since launch, we have already been racing toward the finale of Galactic Disaster Season 1.
