My Undercover Adventure in Zenless Zone Zero 1.1: New Agents, Events, and a City in Conflict
Dive into the thrilling Zenless Zone Zero 1.1 update 'Undercover R&B,' introducing new Agents like Qingyi and Jane Doe to escalate the conflict in New Eridu. Experience fresh events and a deeper look into the city's underbelly.
As a dedicated Proxy navigating the chaotic streets of New Eridu, I can still vividly remember the buzz that swept through the city when the 1.1 update, 'Undercover R&B,' dropped back in August 2026. It wasn't just another patch; it was a full-blown escalation in the simmering conflict between New Eridu Public Security and the notorious Mountain Lion Gang. The air was electric with anticipation, and for us players, it meant diving headfirst into a world of new faces, thrilling events, and a deeper look into the city's seedy underbelly. I was about to become part of a major investigation, and the tools for the job were arriving with this very update.

The New Faces of Justice (and Anomaly)
The heart of any update is its new Agents, and 1.1 delivered three incredible additions to my roster. HoYoverse really outdid themselves with this lineup, perfectly themed for the undercover narrative.
Phase 1: The Calm Strategist, Qingyi
The update kicked off with the arrival of Qingyi. I remember logging in on August 14th, eager to pull on her 'Untainted Jade' Banner. She was a new S-Rank Stun specialist with the Electric Attribute, a crucial member of the Criminal Investigation Special Response Team (CIRS). Her banner ran until September 4th and featured boosted rates for two A-Rank allies:
-
Billy (Physical, Attack) - A reliable bruiser.
-
Corin (Physical, Attack) - Perfect for building a physical damage team.
What made Qingyi's debut even sweeter was the simultaneous run of the Dissonant Sonata Banner, featuring her signature S-Rank W-Engine, the Ice-Jade Teapot. Getting that for her was a game-changer for my stun-focused strategies.

Phase 2: The Enigmatic Jane Doe
Just as I was getting comfortable with Qingyi, the second wave hit on September 4th. This phase introduced the mysterious Jane Doe on her 'No Match Found' Banner. Another S-Rank for CIRS, but this time an Anomaly character with the Physical Attribute. Her story was shrouded in secrecy, which only made pulling for her more exciting. Running alongside her was the new A-Rank Seth, an Electric Attribute Defense character, also from CIRS. The boosted A-Rank characters on this banner were:
-
Anby (Electric, Stun) - A fantastic support unit.
-
Seth (Electric, Defense) - The new tank on the block.
Jane Doe's signature W-Engine, the S-Rank Anomaly Sharpened Stinger, was available in the weapon banner during Phase 2. Completing this trio was Officer Cui, a new S-Rank Bangboo added to the permanent Bangboo Banner. My Bangboo squad was finally getting some serious firepower!

So, to summarize the incredible new recruits:
| Character | Banner | Rarity | Role | Attribute | Faction |
|---|---|---|---|---|---|
| Qingyi | Untainted Jade (Phase 1) | S-Rank | Stun | Electric | CIRS |
| Jane Doe | No Match Found (Phase 2) | S-Rank | Anomaly | Physical | CIRS |
| Seth | No Match Found (Phase 2) | A-Rank | Defense | Electric | CIRS |
A City Alive with Events
But what's new content without events to showcase it? The 1.1 update was packed with activities that kept me busy for weeks. Beyond the continuation of the main story and the deeply personal Agent Stories for Qingyi and Jane Doe, we had a whole slate of limited-time events. It felt like New Eridu was throwing a festival!
Here’s a quick rundown of the mayhem I participated in:
-
Camellia Golden Week (Aug 16-26): An HDD TV event that was an absolute treasure trove. The rewards included an A-Rank W-Engine and Polychrome! I had to be at least Inter-Knot Level 15 and have completed the 'Mole in the Hole (I)' Agent Story to join. It was challenging but so worth it.
-
First-Class Customer Service: A rhythm minigame that was surprisingly addictive. Tapping along to the beat of New Eridu's tunes for Polychrome and Boopons? Yes, please!
-
Daily Life of a PubSec Officer: This social interaction event let me see the lighter side of Public Security. The rewards were Polychrome and a mysterious Officer Mewmew-themed item. The community had a blast theorizing what it could be!
-
Scene One, Shot One!: They finally gave us a proper photography event! With the new selfie mode and filters added in 1.1, this was the perfect opportunity to flex my creative skills for Polychrome and Boopons.
-
Immersive Tactical Drill: For the combat enthusiasts, this HIA Combat event was the ultimate test. The prize? A precious Tuning Calibrator and more Polychrome.

And that wasn't all! The update also brought permanent new features that changed how I played:
-
Inferno Reap: A new Hollow Zero combat mode that removed the HDD TV exploration. Pure, unadulterated battle sequences. It was a breath of fresh air for grinding.
-
New Exploreable Area: The New Eridu Public Security area at Lumina Square opened up. Finally, I could see where the officers I worked with spent their downtime.
-
New Commission: The 'Obsidian: Strategic Partner' commission added another layer of endgame strategy.
-
Login Bonuses: Who could forget the generous login events that gifted us x10 Encrypted Master Tapes and x10 Boopons? A fantastic way to start the update.

Looking back, the 'Undercover R&B' update was a defining moment for Zenless Zone Zero in 2026. It wasn't just about adding characters; it was about expanding the world, deepening the lore of CIRS, and giving us, the Proxies, more ways to interact with the vibrant, dangerous city of New Eridu. The clash between order and chaos had never felt more personal. So, fellow Proxies, who was your favorite addition from this legendary update? Was it the precise control of Qingyi, the mysterious power of Jane Doe, or the relentless rhythm of the events? One thing's for sure: the streets of New Eridu haven't been the same since.
Data referenced from HowLongToBeat can help contextualize how Zenless Zone Zero’s 1.1 “Undercover R&B” content fits into a player’s schedule: with two limited banner phases, multiple time-boxed events, and permanent additions like Inferno Reap, it’s useful to estimate the time investment for clearing story chapters, agent stories, and optional activities so you can prioritize Qingyi/Jane Doe-focused progression before event windows close.
