Zenless Zone Zero version 2.5 update ‘To Be Fuel for the Night’ launches December 30

Ye Shunguang's debut, enhanced optimizations, and additional rewards.

The version 2.5 update for Zenless Zone Zero, dubbed “To Be Fuel for the Night,” will launch on December 30, developer miHoYo announced.

Here is an overview of the update, via miHoYo:

The major update propels Proxies into the culminating chapter of Season 2, introducing the upcoming Void Hunter Ye Shunguang, the popular Zhao, a series of highly anticipated events—including expanded Hollow gameplay and multiplayer combat—and extensive optimizations. To celebrate the new year and express gratitude for the Proxies’ support, Version 2.5 will also grant Proxies a free S-Rank Agent Zhao, 1,000 Polychromes, a new outfit for Jane, and additional rewards.
Ye Shunguang, the young senior disciple of Yunkui Summit, rises as the first dual-form Void Hunter. With her unique attribute Honed Edge, Ye Shunguang can enter the Enlightened Mind state and activate her signature Ether Veil to unleash massive Honed Edge damage while applying a vulnerability effect to enemies. Accompanying Ye Shunguang is her sidekick Bangboo Sprout, who peppers enemies with volleys of flying swords. Joining them is the unbeaten legend of Krampus, Zhao, who is an S-Rank Ice Defense Agent. Despite her adorable appearance, Zhao weaves swiftly across the battlefield and launches assaults with her massive weapon to suppress enemies. By accumulating Frostbite, Zhao can trigger Ether Veil: Wellspring, granting powerful buffs for the entire squad.
With strengthened allies, the new chapter unveils the final moments of Waifei Peninsula’s escalating crisis. The legendary Qingming Sword has begun to resonate with the primordial power of the Creator—an overwhelming force that assisted Proxies in past battles but now threatens a profound backlash for Ye Shunguang. Meanwhile, mysterious white flowers—once found only within the Hollows—have begun blooming across Failume Heights, signaling the dangerous expansion of the Lemnian Hollow. Proxies shall venture deep into the Lumite Mine ruins, using their new Perception Technique and teaming up with allies to uncover the truths hidden within the Hollow’s depths.

The adventure continues in the epilogue Sword Seeker Chronicles as Proxies support Ye Shunguang in seeking a remedy for the Qingming Sword’s backlash. The investigation showcases Ye Shunguang’s Bladeflash Mirage ability and offers exclusive rewards, including a brand-new W-Engine. Multiplayer combat arrives in the limited-time event Joint Investigation: The Divine Maze, where three-member squads face fast-paced cooperative challenges that reward coordination and tactical timing. Outside combat, the newly added Proxy Outpost allows Proxies to join or create outposts, facilitate discussions, and post or accept commissions, making New Eridu more connected than ever.
Version 2.5 also introduces quality-of-life updates that refine combat and progression. The existing Agents Soldier 11, Grace, Soldier 0 – Anby, Ellen, and Burnice will be enhanced with updated mechanics and performance boosts, with additional agents in the standard Stable Channel scheduled for future enhancements. Meanwhile, improvements to Shiyu Defense and Deadly Assault further polish the gameplay loop, while the new sweep function for Combat Simulation stages lets players consume Ether Batteries to instantly gather promotion materials and Drive Discs, easing the burden of day-to-day progression.
To welcome both new and returning Proxies, all players can jump directly into Version 2.5’s story through Advance Screening, while expanding their squads with a lineup of limited-time channels. The channels for Ye Shunguang and Zhao will run throughout the entire version, and a special rerun channel in the latter half guarantees the first S-Rank signal obtained will be a selected character among Alice, Soldier 0 – Anby, or Astra, along with their signature W-Engines returning with the same guarantee mechanic.

Zenless Zone Zero is available now for PlayStation 5, Xbox Series, PC via client download and Epic Games Store, iOS via App Store, and Android via Google Play.
