on

For every Proxy navigating the neon-drenched streets of New Eridu, the night of December 30, 2025 marks a defining turning point. Zenless Zone Zero Version 2.5, “To Be Fuel for the Night,” is now live—bringing the explosive conclusion of Season 2, the arrival of long-requested real-time co-op, sweeping quality-of-life upgrades, and one of the most generous reward drops the game has seen so far.

This is far more than a story patch. Version 2.5 reshapes how Zenless Zone Zero is played, from social systems and endgame progression to character balance and daily farming. Whether you’re returning for the finale or diving in fresh, this complete guide breaks down everything new in ZZZ 2.5, what to prioritize first, and why this update sets the foundation for the future of New Eridu.

🗡️ The Grand Finale of Season 2

Version 2.5 delivers the long-awaited conclusion to the Waifei Peninsula saga with Main Story Chapter 6: “To Be Fuel for the Night.”

The narrative opens with the appearance of strange white Hollow-born flowers across Failume Heights, an unsettling phenomenon tied to the legendary Qingming Sword. Alongside Zhao of the Krampus Compliance Authority, Proxies investigate the expanding Lemnian Hollow, pushing deeper than ever before into its corrupted depths.

New explorable areas such as the Lumite Mine introduce tougher encounters, higher stakes, and the final revelations behind the Exaltists’ conspiracy. The update also introduces the Buyan Store, a new progression layer that allows players to trade rare items discovered in these zones for valuable rewards—adding more incentive to explore every corner of the new content.

🆕 The Headliners: New S-Rank Agents & Banners

Zenless Zone Zero 2.5 Update Guide & Season 2 Finale Breakdown

Version 2.5 introduces two powerful S-Rank Agents, both integral to the story and available throughout the patch cycle.

🔥 New Agents Overview

Ye Shunguang

  • Rarity / Role: S-Rank, Attack

  • Attribute: Honed Edge (Physical)

  • Why She Matters:
    Zenless Zone Zero’s first true dual-form Void Hunter, Ye Shunguang revolves around building Qingming Sword Force to enter an Enlightened Mind state. In this form, she unleashes devastating Physical damage and high-skill combo potential.
    Pull if: You want a top-tier Physical DPS and enjoy mechanically demanding, transformation-based gameplay.

Zhao

  • Rarity / Role: S-Rank, Defense

  • Attribute: Ice

  • Why She Matters:
    Zhao is a highly versatile HP-scaling support who provides team-wide healing, powerful Ether Veil buffs, and the ability for allies to ignore enemy resistances.
    Best part: She is completely free via the Special Visitor login event, making her one of the most valuable free Agents ever released.

🎯 Strategic Banner Schedule

Phase 1 (December 30, 2025)

  • Debut banners for Ye Shunguang and Zhao

  • Signature W-Engines: Cloudcleave Radiance and Half-Sugar Bunny

Phase 2 (January 21, 2026)

  • Introduction of the Exclusive Rescreening Banner

  • Features Alice, Soldier 0 Anby, and Astra Yao

  • Allows players to select their guaranteed S-Rank target, completely bypassing the usual 50/50 system for the first pull

This banner alone dramatically shifts long-term pull strategy and reduces gacha frustration.

🔄 Transformative New Systems & Gameplay

Beyond characters and story, Version 2.5 introduces systems that fundamentally change how players interact with Zenless Zone Zero.

🤝 First-Ever Co-Op Combat: Joint Investigation

The highly anticipated real-time multiplayer finally arrives with the limited-time event:

Joint Investigation: The Divine Maze

  • Duration: January 3 – January 22

  • Players: 3-player PvE

  • Core Mechanic: Shared Chain Overdrive meter for synchronized team attacks

This mode emphasizes coordination, role synergy, and timing—marking a major step toward community-focused gameplay.

🏠 Enhanced Social Play: Proxy Outposts

The new Proxy Outpost system functions as Zenless Zone Zero’s official guild feature.

Key highlight: the Intel Board, where players can post difficult commissions—such as Notorious Hunts—for Outpost members to complete on their behalf. You still receive the rewards, making this system a powerful tool for time-constrained players and social-focused Proxies alike.

🔧 Empowering Your Roster: Potential Vision System

Version 2.5 breathes new life into older characters with the Potential Vision System.

The following Agents receive major upgrades:

  • Soldier 11

  • Grace

  • Burnice

  • Ellen

  • Soldier 0 Anby

By spending Daily Performance currency, players can unlock up to six tiers of new combat effects and stat bonuses, making previously overshadowed Agents viable again in endgame content.
