Zenless Zone Zero wrapped up 2025 with a bang, and Version 2.5 proves that HoYoverse isn’t slowing down anytime soon. Launched on December 30, 2025, this update dives deeper into New Eridu’s evolving power balance with two standout Agents, their signature W-Engines, and story-rich events that reward both skill and commitment.
Whether you’re chasing a new DPS peak, stronger team synergies, or just more reasons to jump back into the Hollows, Version 2.5 has something lined up for every Proxy. In this article, we’ll break down the new Agents Ye Shunguang and Zhao, take a closer look at their signature W-Engines, and walk through the major events you won’t want to miss.
New Agents: Ye Shunguang and Zhao
Ye Shunguang is a core member of Yunkui Summit and bears the title Void Hunter: Qingming Arbiter, serving as a calm and disciplined enforcer who restores balance when Hollows run rampant. In combat, she is a Physical-Attack Agent built for flashy players, centered on managing her Enlightened Mind state and Qingming Sword Force to unleash relentless aerial slashes, fluid invulnerability transitions, and devastating finishers. Her Ether Veil: Verdict mechanic allows her damage to bypass enemy Stun multipliers, making her lethal even outside of traditional burst windows. Once fully set up, Ye Shunguang excels as a primary on-field DPS who thrives in teams that can feed her buffs, maintain Ether Veils, and give her uninterrupted time to dominate the battlefield.
Zhao takes a very different but equally important role as an Ice-Defense Agent from the Krampus Compliance Authority, New Eridu’s no-nonsense enforcers of order. Gameplay-wise, Zhao is a tank-support hybrid who scales heavily with HP, turning survivability into momentum. By building and consuming Frostbite Points, she triggers Ether Veil: Wellspring to grant her squad HP boosts, ATK buffs, healing, and powerful Quick Assist chains. Her kit encourages smart parries, controlled pacing, and defensive rotations that gradually showball fights in your favor. Zhao pairs exceptionally well with aggressive carries like Ye Shunguang, anchoring the frontline and ensuring sustained damage without letting the team collapse.
Both Ye Shunguang and Zhao are available in their own featured banners, alongside A-Rank Agents Nicole and Lucy, until February 5, 2026.

New W-Engines
Cloudcleave Radiance is Ye Shunguang’s signature W-Engine, and it’s built to push her damage ceiling even higher. With a massive 743 Base ATK and 48% Crit DMG, it immediately boosts her offensive potential. Its passive effect allows Attack Agents to ignore 20% of enemy Physical RES, and whenever an Ether Veil is activated, it grants a hefty DMG and Crit DMG increase for 40 seconds. This makes it a perfect match for Ye Shunguang’s aggressive, veil-driven playstyle, rewarding clean execution and sustained pressure.
Half-Sugar Bunny is Zhao’s signature W-Engine and a dream tool for Defense Agents who want to support without sacrificing presence. It offers 713 Base ATK and a chunky 30% HP boost, improving Zhao’s scaling. Its passive effect regenerates Energy while granting the entire squad bonus ATK and Max HP, with an added burst of Crit DMG whenever an Ether Veil is activated or extended. Since only one instance of its squad buff can exist, it firmly positions Half-Sugar Bunny as a cornerstone support weapon that elevates any defensive core.
New Events
Sword Seeker Chronicles is a story-driven event that puts Ye Shunguang front and center. Proxies can head to Suibian Temple in Failume Heights to explore the Qingming Realm with her, uncovering ways to overcome the Qingming Sword’s dangerous side effects. Inside the realm, players gain special abilities and access to trials that enhance Ye Shunguang through Sword Will Resonance. Completing limited-time missions rewards you with the exclusive W-Engine Cauldron of Clarity, Polychromes, and valuable upgrade materials.
Joint Investigation: The Divine Maze shifts the focus to cooperative combat and mastery. Taking place in Failume Heights, this event introduces both Solo and Join Investigation modes, with multiplayer stages ranging from Standard to Nightmare difficulty. It’s a great test of coordination and squad efficiency, especially at higher tiers. Completing stages earns you exclusive cosmetics like the “Maze Exit” namecard, unique titles, Polychromes, and upgrade materials, making it a must-play for both completionists and casual players.
Version 2.5 is a confident step forward for Zenless Zone Zero, blending high-skill Agents, meaningful gear upgrades, and events that reward both lore lovers and hardcore players.
