Zenless Zone Zero Version 3.1 “The Long Goodbye” Phase I: New Agents, W-Engines, Story and Events
Zenless Zone Zero Version 3.1, titled “The Long Goodbye,” is now live with two S-Rank Agents, two S-Rank W-Engines, a new main story chapter, and several anniversary events. The Phase I update launched on July 29, 2026, giving Proxies a mix of new combat options, story content, free rewards, and limited-time activities.
Version 3.1 Phase I: What’s New?
The biggest additions in Version 3.1 are Remielle and Aria, along with their featured W-Engines. Both Agents belong to the Anomaly specialty, but they use different attributes. Remielle is a Lumiflux - Anomaly Agent, while Aria uses Ether - Anomaly.
The update also adds the main story chapter “The Long Goodbye.” Alongside the story, players can take part in anniversary activities such as Marcel Anniversary Gift, Filmgoer Thank-You Gift, and Summer Waves Roll In. The official Phase I overview also highlights additional activities, including login rewards, trial content, photography-themed gameplay, and returnee events.

New S-Rank Agents Arrive in Version 3.1
Remielle and Aria are the two featured S-Rank Agents introduced through the Version 3.1 Phase I Signal Search channels. Their shared Anomaly role gives players two new options for teams built around Anomaly-focused combat.
Remielle is particularly important to the update because she is presented as one of the first-generation Void Hunters. Her character also receives new story and trust-related content during Version 3.1. Aria, meanwhile, returns as an Ether Anomaly Agent and is described as the lead vocalist and face of her band, despite being a robot.
Remielle vs. Aria
| Agent | Rank | Attribute | Specialty | Version 3.1 Role |
|---|---|---|---|---|
| Remielle | S-Rank | Lumiflux | Anomaly | New Agent and first-generation Void Hunter |
| Aria | S-Rank | Ether | Anomaly | Featured Agent and returning character |
The two Agents also arrive alongside their respective S-Rank W-Engines. Remielle is associated with Ode of Resurrected Wings, while Angel in the Shell accompanies the Aria side of the Phase I Signal Search content.
The introduction of two Anomaly Agents makes Version 3.1 particularly relevant for players looking to experiment with different Anomaly team combinations. Instead of being limited to new story content, the update gives players new ways to approach combat and roster building.
New S-Rank W-Engines
Version 3.1 adds two S-Rank W-Engines designed for the new Phase I lineup. The new options are Ode of Resurrected Wings and Angel in the Shell, both listed under the Anomaly category.
These W-Engines are available through the limited-time Signal Search content connected to the Version 3.1 launch.
For players deciding where to spend their resources, the important distinction is that the update not only introduces new Agents. It also provides corresponding high-rarity equipment, giving players another limited-time target during the Phase I banners.
“The Long Goodbye” Adds a New Main Story Chapter
Version 3.1's main narrative addition is the new chapter “The Long Goodbye.” The chapter forms the update's central story content and continues the broader narrative of New Eridu and its characters.
The title itself suggests that farewell is an important part of the chapter’s theme. HoYoverse describes the story with the question of whether what comes next is a prelude to tomorrow or the finale of a farewell.
Version 3.1 also expands character-focused content beyond the main story. New Agent Trust Events and Quality Time Events are available for Remielle and Sigrid, giving players additional interactions with the new characters and their stories.
Why the Story Content Matters
The update combines the main chapter with character-specific activities rather than treating the story as a standalone addition. This gives players several ways to explore the new cast while progressing through Version 3.1.
For players returning after a break, the mix of a new story chapter, new Agents, and anniversary activities makes Version 3.1 a strong reason to return.
Marcel Anniversary Gift Brings Major Free Rewards
Marcel Anniversary Gift is one of the most important reward-focused additions in Version 3.1. The event allows eligible players to claim a limited S-Rank Agent, an S-Rank W-Engine, Polychromes, and other rewards.
This is separate from the normal Signal Search system, so the anniversary reward structure gives players another way to strengthen their account without relying entirely on limited character pulls.
Other Version 3.1 Login Rewards
Version 3.1 also includes additional login-based rewards that provide Encrypted Master Tapes and Boopons. The official version information lists Gift From the Clouds, which awards Encrypted Master Tape ×10 after seven days of logins, while The Great “En-Nah” Giveaway! provides another Encrypted Master Tape ×10 and Boopon ×10 for seven days of login participation.
These rewards are especially useful for players saving resources for future Signal Searches.
Filmgoer Thank-You Gift and Other Events
Filmgoer Thank-You Gift adds another reward track to the Version 3.1 anniversary lineup. The event offers an S-Rank Agent or W-Engine, a Remielle dynamic wallpaper, menu decoration sets, and additional rewards through cumulative top-ups.
Because this event is tied to cumulative top-ups, it works differently from the free anniversary reward events. Players should therefore distinguish between login rewards, event rewards, and paid progression when planning how to participate.
Summer Waves Roll In provides a separate seasonal event experience. Its theme centers on the sea, summer adventures, and a bonfire atmosphere, giving Version 3.1 content a lighter seasonal element alongside the more serious story chapter.
Other activities listed for the 3.1 update include Snap! Focus Showdown!, Crispy Meal Deployment Plan, Dangerous Fugitive’s Leisurely Vacation, and Ding-Dong! Delivery Training in Progress. The update also introduces the new combat gameplay “Enigma of the Labyrinth: Operation Bagel.”
What Players Should Prioritize in Version 3.1
Players with limited time should start with the main story and time-sensitive rewards. The story chapter “The Long Goodbye” adds the core narrative. At the same time, events such as Marcel Anniversary Gift and the login campaigns offer rewards that may be tied to limited event periods.
For players focused on character progression, evaluate Remielle and Aria alongside their W-Engines, not separately. Their Anomaly roles and the availability of Ode of Resurrected Wings and Angel in the Shell make the Phase I Signal Searches particularly relevant for players building Anomaly-focused teams.
Players interested in the broader anniversary content can then move to Summer Waves Roll In and the other temporary activities.
Official Zenless Zone Zero merchandise and character-related collectibles are also likely to attract attention during major anniversary updates. For North American fans, retailers such as Animon Life can be relevant when looking for officially licensed merchandise tied to the game’s characters and wider releases.
