Version 1.2.1 / 1.2.2 Patch Notes

It’s December, and that means it’s time for the final roadmap update for Daemon X Machina: Titanic Scion. As promised, we’re adding in three new boss battles that should test even the most-skilled Arsenal pilots. Starting today, you’ll be able to challenge Chaldia, Insania Rex RT: Ω, and Immortal Void RT: Ω through the Rematch Simulator. You can get a look at these imposing foes below.

Additionally, these new battles are joined by a wealth of gameplay adjustments that will improve the experience and address issues impacting game progress.

Lastly, all digital editions of Daemon X Machina: Titanic Scion are also available for 30% off through January 5, 2026 (10AM PT), along with select DLC. Combined with these latest updates and fixes, there’s no better time to recruit some more friends for co-op than this holiday sale season.
