Marvelous Inc. has released Update 1.1.1 for Daemon X Machina: Titanic Scion, bringing new bosses, cosmetics, and several gameplay improvements to the high-octane mech action sequel. This update introduces two powerful new foes, Lapis Lacrima RT: Ω and Cybele RT: Ω, which are now available as rematch encounters at the base’s Rematch Simulator. In addition, the previously limited-time Zeruchroar boss event is now permanently accessible, allowing players to challenge this formidable adversary whenever they wish.
The update also includes a variety of additions, balance tweaks, and bug fixes aimed at improving performance and playability. Players can now toggle visible mutations after unlocking Fusion, while two new cosmetic DLCs—“Formal Suit Outfit” and “Axiom Researcher Outfit”—are available for free. Additional adjustments include new Stray and Immortal encounters tied to specific missions, expanded post-game mission access, and a long list of fixes addressing weapon duplication, mission errors, and visual glitches.
