Zenless Zone Zero 2.5 “To Be Fuel for the Night”: The Ultimate Guide to the Final Season 2 Update

The climactic finale to Zenless Zone Zero’s Season 2 has finally arrived. With the Version 2.5 update, titled “To Be Fuel for the Night,” HoYoverse delivers one of the largest and most transformative patches in the game’s history. Released on December 30, 2025, this update doesn’t just wrap up the Waifei Peninsula storyline—it introduces major gameplay systems, generous rewards, and long-requested quality-of-life improvements that redefine how Proxies experience New Eridu.

Whether you’re a long-time player or someone returning after a break, this comprehensive guide breaks down everything you need to know about Version 2.5—from the story finale and new agents to co-op gameplay, social systems, and smart progression tips.


๐Ÿ”ฅ Why Version 2.5 Matters

Zenless Zone Zero 2.5 stands out because it represents a clear turning point for the game:

  • It delivers the final chapter of Season 2, closing a major narrative arc

  • Introduces the first dual-form agent in ZZZ history

  • Launches the game’s first real-time co-op PvE mode

  • Adds guild-like social features that encourage community play

  • Implements time-saving QoL systems that directly address player feedback

Within the community, Version 2.5 is already being viewed as a “soft relaunch”—a foundation that prepares Zenless Zone Zero for a much larger 2026 roadmap.


๐Ÿ—ก️ Story Finale: To Be Fuel for the Night

The main commission of Version 2.5 brings the Waifei Peninsula arc to its dramatic conclusion. The legendary Qingming Sword begins resonating uncontrollably, triggering dangerous backlash effects that threaten its wielder, Ye Shunguang. At the same time, unsettling white flowers begin appearing across Failume Heights, signaling deeper Hollow corruption and a looming catastrophe.

Joined by Zhao of the Krampus Compliance Authority, Proxies venture into newly expanded Hollow zones, including the depths of the Lumite Mine ruins. Here, the true scope of the Exaltists’ conspiracy is revealed, culminating in a decisive battle that will determine the peninsula’s fate.

After the main chapter concludes, the Sword Seeker Chronicles event acts as an epilogue, offering additional challenges, lore insights, and exclusive rewards tied to the legacy of the Qingming Sword.


๐Ÿ‘ฅ New Agents: Ye Shunguang & the Free S-Rank Zhao

Zenless Zone Zero 2.5 “To Be Fuel for the Night”: Guide to the Final Season 2 Update

Ye Shunguang — Dual-Form Void Hunter (S-Rank, Attack)

Ye Shunguang is the first agent in Zenless Zone Zero to feature a dual-form combat system. As a Physical Honed Edge specialist, she can transition into an “Enlightened Mind” state that dramatically boosts damage output, applies vulnerability debuffs, and enables powerful Ether Veil interactions.

Her kit rewards precise timing and mechanical mastery rather than brute force, giving high-skill players a new ceiling to push. Ye Shunguang is accompanied by her Bangboo, Sprout, which assists in combat with ranged flying sword attacks. She also introduces a new Drive Disc set, White Water Ballad, designed to enhance Critical Rate while Ether Veil effects are active.


Zhao — Ice Defender (S-Rank, FREE)

In one of the most generous moves in the game’s history, Zhao, a limited S-Rank Defense agent, is available for free to all players during Version 2.5 via the Special Visitor login event.

Zhao scales with Max HP and excels as a high-utility Ice defender, offering:

  • Teamwide healing

  • Ether Veil activation for allies

  • Buffs that allow teammates to bypass enemy resistances

Her signature W-Engine, Half-Sugar Bunny, further boosts Attack, Max HP, and Critical Damage across the entire squad. Community consensus already places Zhao among the most universally valuable agents in the game, especially for free-to-play and low-investment teams.


๐Ÿ—“️ Banner Schedule & Reruns

Version 2.5 is divided into two banner phases:

Phase 1 (December 30 – January 21)

  • Ye Shunguang featured banner

  • Zhao featured banner

  • Signature W-Engine banners

Phase 2 (Starting January 21, 2026)

  • “Exclusive Rescreening” rerun banner

  • Choose one rate-up S-Rank target from Alice, Soldier 0 – Anby, or Astra Yao

  • Their signature W-Engines follow the same selection rule

This flexible rerun format allows players to target specific characters without relying purely on chance.


๐ŸŽฎ New Gameplay & Social Systems

๐Ÿค Joint Investigation: Divine Maze (3-Player Co-Op)

Version 2.5 introduces Zenless Zone Zero’s first real-time co-op PvE mode. In this limited-time event, teams of three Proxies tackle themed stages with unique objectives, such as triggering a specific number of Ultimate attacks.

Key features include:

  • Reviving fallen teammates

  • A shared Chain Meter for synchronized Chain Attacks

  • Role suggestions (DPS, Break, Support) to encourage balanced teams

Success depends on coordination and synergy rather than raw stats, making this mode a highlight for cooperative play.


๐Ÿ  Proxy Outposts & Intel Board

Proxy Outposts act as guild-like social hubs where players can create or join communities based on shared interests. The integrated Intel Board allows members to post and accept commissions for challenging content such as Notorious Hunts, creating a player-driven support ecosystem.


๐Ÿ›️ Buyan Store & New Exploration Progression

The Buyan Store, located in Failume Heights, introduces a new progression system. By exploring areas like the Lumite Mine and collecting rare items, players can increase their Mystery Rank, unlocking valuable rewards and long-term bonuses.


๐Ÿ”ฎ Agent Potential Vision System

A new Agent Potential Vision progression system allows older agents to receive meaningful upgrades. Characters such as Soldier 11, Grace, and Burnice are the first to benefit, gaining new mechanics and enhanced combat performance through Daily Performance currency.


⚙️ Major Quality-of-Life Improvements

Version 2.5 delivers some of the most impactful QoL changes to date:

  • Quick Sweep Function – Instantly clear Combat Simulation and Area Patrol stages using Ether Batteries

  • Drive Disc Auto-Dismantle – Automatically dismantle unwanted disc rarities on pickup

  • Targeted Sub-Stat Tuning – Guarantee upgrades to selected Drive Disc sub-stats using Resonating Cores

  • Shiyu Defense Revamp – Streamlined Critical Nodes and a new points-based scoring system

These changes significantly reduce daily grind and make character optimization far more approachable.
