Zenless Zone Zero 2.6 Update: New Agents, Events, and Compensation

Zenless Zone Zero's Version 2.6 update, 'Encore for an Old Dream,' arrived on February 6, 2026 after a roughly five-hour maintenance. The patch runs for 46 days, ending on March 24, 2026 at 06:00 (UTC+8), giving players a long runway to meet the new S-Rank Agents Sunna and Aria, explore the 404 Error Livehouse, and claim the compensation mail. This update is especially busy because it combines two new Agents, idol-themed events, story content, endgame balancing, and a hefty list of fixes in one package.

Compensation and Platform Update Guide

The update includes two types of compensation. Both require players to reach Inter-Knot Lv. 4 before February 6, 2026 at 06:00 (UTC+8).

• Server Update Compensation: Polychrome ×300, claimable until the end of Version 2.6.

• Issue Fix Compensation: Polychrome ×300, claimable before March 8, 2026 at 23:59 (UTC+8).

Both rewards arrive through in-game mail after the update. The mail expires after 30 days, so players should not leave those attachments sitting around. The update process depends on the platform:

• PC: Exit the game, restart, then select update.

• Android: Follow the in-game pop-up instructions.

• iOS: Go to the App Store and select update.

• PS5 or PS5 Pro: Open the PS5 home screen, highlight Zenless Zone Zero, hold the Options button, then check for updates.

• Xbox Series X|S: Open the Xbox dashboard, go to My games & apps, select Manage, then confirm the update for Zenless Zone Zero.

New Agents, W-Engines, and Bangboo

Version 2.6 adds two S-Rank Agents with very different combat identities.

Type	Item	Role	Signal Search
S-Rank Agent	Sunna	Physical - Support	Whimsy in Triple Meter
S-Rank Agent	Aria	Ether - Anomaly	Neon Angel
S-Rank W-Engine	Thoughtbop	Support	Dissonant Sonata
S-Rank W-Engine	Angel in the Shell	Anomaly	Dazzling Choir
S-Rank Bangboo	Biggest Fan	Partner	An Outstanding Partner

Sunna functions as a squad-wide buffer. Her EX Special Attack grants Angelic Chord-ination to all Agents and can activate Ether Veil: Delusion Reprise, which boosts the ATK of the whole squad. She can also inflict Cat's Gaze on enemies, creating bonus damage based on the specialty of the Agent who triggers the effect.

Aria is an Ether Anomaly DPS. She charges her Basic Attack: Perfect Pitch to deal Ether DMG and can trigger Abloom for substantial additional Attribute Anomaly DMG. When an enemy is Stunned, Abloom gets an even larger boost. Players who want a new Anomaly damage dealer should keep an eye on the Neon Angel Signal Search.

Story, Outfits, and the New Area

Season 2 Interlude 'Encore for an Old Dream' is permanently available after the Version 2.6 update. To access it, players need to complete Main Story Season 2 Chapter 6 'To Be Fuel for the Night.' The update also adds the Side Missions 'Dawn-Sent Whisper' and "Today's Weather is Unknown," plus new Agent Trust Events and Quality Time Events for Sunna and Aria.

The new area is 404 Error Livehouse, which unlocks after the update. Existing areas such as Sixth Street, Waifei Peninsula, and Lumina Square also receive festive decorations for Gilded Carrot Day.

Outfit collectors have three additions to consider:

• Sunna: Afternoon Tea Break — available from the update until May 6, 2026 at 05:59 (UTC+8). Discounted price: Monochrome ×1,350. Regular price: Monochrome ×1,680.

• Aria: Discordant Note — available from March 4, 2026 at 12:00 (server time) until May 6, 2026 at 05:59 (UTC+8). Discounted price: Monochrome ×1,350. Regular price: Monochrome ×1,680.

• Pan Yinhu: Culinary Jewel — earned through limited-time reward missions in the 'A Harmony of Delusions' event.

Version 2.6 adds several collection and interface upgrades. Dynamic wallpapers for Sunna and Aria are available by obtaining the Agent and raising Trust Level. Agent Aria also receives two forms within the City, and both new Agents have idle animations. Recruiting all three Angels of Delusion members unlocks the dynamic wallpaper 'Delusions in Progress.'

Other notable additions include new Proxy accessories, a speed-up function for daily training stage completion animations, new achievements and hidden achievements, the Threshold Simulation: Myriad Endgame badge set, new titles, new exchangeable accessories at Suibian Temple - Devon Pawnshop, and the Sweet Daydream pendant and menu decoration set.

For combat and interface quality of life, there is a new Combat Data function for Shiyu Defense and Deadly Assault results, a Training Target tab in Compendium - Training, new camera filters, frames, and a Sticker feature, a commission progress percentage on the main HDD interface, and improved Restart options with Start Over and Retry Challenge functions. A Gilded Carrot Day celebratory mail also arrives with an Auspicious Golden Carrot item, which grants 1 Ether Battery and a commemorative item.

Endgame Updates: Shiyu Defense, Deadly Assault, and Hollow Zero

Shiyu Defense Critical Node receives new buff phases. Phase I favors Electric, Fire, and Physical DMG while boosting CRIT DMG and Energy. Phase II adds Ether Veil ATK and CRIT DMG bonuses, Ice DMG, and Max HP. Phase III leans into Physical, Electric, and Ether DMG with Ether Veil ATK and RES-ignoring effects. Phase IV boosts overall ATK, CRIT DMG, Stun multipliers, and squad-wide ATK after Attribute Anomaly triggers.

Deadly Assault rotates in new enemy lineups:

Phase	Enemies
Phase I	Primordial Nightmare - The Creator, Miasma Priest, Notorious - Dead End Butcher
Phase II	Discordant Solo - Vesper, The Defiler, Wandering Hunter
Phase III	Miasmic Fiend - Unfathomable, Miasma Ravager - Sobek, Notorious - Pompey

Threshold Simulation: Myriad Endgame Hard Mode gets a new scoring system based on the best total battle score across three Battle nodes' Final stages. Resetting a lineup will not reset the Best Total Score and Ranking. Exclusive avatars 'Discovering Truths' and 'Everburning Heart,' plus the title 'The Multifaceted Hollow Detective,' are also available.

Hollow Zero receives a big update. The Investigation Progress level cap increases from 220 to 260, and a new Operation Matrix mode arrives with different weekly environments and Initial Supplies. A fourth Auxiliary Agent slot is now available in Operation Matrix, supported by Auxiliary Assist and Auxiliary Gear. New Reward Progress tracking and Quick Complete functions are also added, along with Deep Cleaning Service Cards and new Tactical Prism Programs for Sunna and Aria.

Battle Trial: Glory will end on March 23, 2026 at 03:59 (server time), with a new mode planned after the Version 2.7 update.

Fixes and Optimizations

This update also addresses a long list of bugs. Some notable fixes include an issue with Banyue's Mindscape 01 in solo combat, Yixuan's Basic Attack displacement, Hoshimi Miyabi's weapon visuals with the Hailstorm Shrine W-Engine, and Ye Shunguang's visual effects. Other corrections cover Alice's Core Passive display, Lucia's Ultimate effects, Soldier 11's Basic Attack after awakening Potential, and Astra Yao's Quick Assist interactions. iOS devices also receive shader loading logic improvements, which should reduce stuttering and lag in certain situations after shaders are fully loaded.
