Zenless Zone Zero 3.1 turns the anniversary into a roster decision

Zenless Zone Zero 3.1 launches on July 29, 2026, and HoYoverse is tying the update’s new story chapter to one of the most consequential account choices the game has offered so far: a free limited S-Rank Agent with that Agent’s corresponding W-Engine. That is the strongest practical development in the ZZZ July 29 update because it changes the usual pre-patch question from “who should I pull?” to “how do I avoid wasting a rare guaranteed upgrade?”

HoYoverse detailed Version 3.1, titled “The Long Goodbye,” in its special program and official update materials, as reported by Siliconera, GamersHeroes, MMOBomb, DayOne, and Game8. The patch adds Remielle Dan, the first Lumiflux attribute Agent, at launch; Sigrid, an S-Rank Ice Attack Agent, in the second half; the permanent mode Enigma of the Labyrinth: Operation Bagel; anniversary rewards; and a set of summer costumes, including one outfit for Lucy that can be earned through an event.

The tension is account planning. Version 3.1 is not a quiet anniversary check-in. Remielle introduces a new attribute system, Sigrid pressures Ice-team planning later in the patch, rerun banners compete for saved Polychromes, and the anniversary selector can hand players a full S-Rank Agent and signature W-Engine pairing. For returning Proxies and resource-tight free-to-play players, the best move before July 29 is to stop treating each reward in isolation. The patch’s value comes from how its banners, free selector, and role coverage overlap.

Remielle is the launch banner, and Lumiflux is the system to watch

HoYoverse is positioning Remielle Dan as Version 3.1’s mechanical centerpiece. Siliconera reports that Remielle is an S-Rank Anomaly Agent and the first character tied to the new Lumiflux attribute. GamersHeroes describes her as a first-generation Void Hunter, while DayOne’s report of HoYoverse’s announcement says her “Attribute Flux” mechanism synchronizes her damage output’s attribute with the attribute of the next Agent in the squad. MMOBomb similarly reports that Remielle can change the attribute of her damage based on the next Agent in the party.

That confirmed detail is the key difference between Remielle and a typical new damage unit. The sources do not provide a full build sheet, final multipliers, best Drive Disc sets, or team rankings, so any claim that she is automatically the strongest Anomaly option would be premature. What is confirmed is more useful for planning: Remielle is designed around team-dependent attribute adaptation, which means her value may scale with the breadth of your roster and the enemies you are preparing to fight.

For progression-minded players, that pushes Remielle into an unusual category. An Anomaly Agent whose damage attribute can follow the next squad member, at least as described by HoYoverse’s materials through multiple outlets, could reduce the pressure to build a separate specialist for every weakness. The tradeoff is complexity. If her output depends on squad order or the next Agent’s attribute, players will need to understand rotation structure, not only raw stats. Before spending Polychromes, players should wait for in-game trial access and final kit text, especially because the sources confirm the broad mechanic but not the complete math.

Remielle’s banner will be available throughout Version 3.1, according to Siliconera and MMOBomb. That extended availability matters. Players do not need to decide on day one unless they are chasing early clears or cosmetics. Since the anniversary selector is also part of the patch, a patient approach is stronger: test Remielle, check whether her Lumiflux behavior fits your existing teams, then decide whether your premium pulls should go toward a new flexible Anomaly core or toward later banners.

Sigrid arrives later, while reruns create a real opportunity cost

Version 3.1’s second new Agent is Sigrid, identified by Siliconera, MMOBomb, GamersHeroes, and DayOne as an S-Rank Ice Attack Agent. GamersHeroes says she uses the Aerial Patrol Spear Form, and DayOne places her in the story through the Airspace Patrol Department alongside Administrative Director Lindverne Sunbringer. Unlike Remielle, Sigrid is scheduled for the second half of the patch, according to Siliconera and MMOBomb.

The banner structure creates a split decision. Siliconera reports that the launch phase includes Remielle and a rerun Aria banner. MMOBomb reports that Sigrid arrives in the second banner period, while the second half also brings back the Exclusive Rescreening channel with reruns of Dialyn, Yuzuha, and Harumasa, letting players choose which of those Agents is the rate-up. MMOBomb adds that the first S-Rank pulled on that channel is guaranteed to be the selected rate-up Agent.

That guarantee, if presented in-game as MMOBomb describes it, is a major planning lever. It means the second half is not simply “Sigrid or skip.” It is Sigrid against a selectable rerun target, after players have already had time to evaluate Remielle. If your account lacks Ice damage and you have the supports or gear to make an Ice Attack Agent useful, Sigrid has a clear role-based argument. If your roster is missing a specific rerun character, the Exclusive Rescreening setup may be a cleaner way to patch a hole than gambling across unrelated banners.

There is one source conflict to note around pre-livestream reporting. LootBar’s June article said HoYoverse had not yet announced the Version 3.1 banner schedule at the time of writing and treated Remielle details as incomplete. LDShop’s June article framed some details as insider data and speculation, including calling Remielle Ether rather than Lumiflux. Later reports based on HoYoverse’s special program identify Lumiflux as the confirmed attribute and provide the banner order. The safer reading is to treat the special program coverage as superseding earlier speculative or incomplete banner posts.

The free S-Rank choice is powerful, but the exact list needs careful reading

The Zenless Zone Zero free S-Rank anniversary gift is the update’s most broadly valuable reward. Siliconera reports that players can log in and receive a pair consisting of an S-Rank character and that character’s tied equipment, with options listed as Soldier 0 Anby, Hugo, Jane Doe, Lucia, or Trigger. GamersHeroes reports the same structure, saying all Proxies can choose between Jane, Soldier 0 Anby, Hugo, Trigger, or Lucia and receive the corresponding exclusive W-Engine. DayOne also reports a free limited S-Rank Agent of choice with a corresponding exclusive W-Engine, plus 1,600 Polychromes and 20 Signal Searches.

MMOBomb’s wording is slightly different, listing “Jane, Soldier 0, Anby, Hugo, Trigger, or Lucia.” Taken literally, that reads like six names, but the other reports frame Soldier 0 Anby as a single option. Because the sources otherwise agree on the giveaway’s structure, players should verify the exact in-game selector on July 29 before making a choice rather than relying on shorthand names across reports.

The practical priority is role coverage, not popularity. If you already own one of the selector characters but lack their W-Engine, the sources do not specify whether the selector handles ownership, duplicates, or W-Engine-only scenarios in a special way. Do not assume a compensation path or duplicate conversion unless HoYoverse’s in-game notice states it. If you are missing several options, choose the Agent whose role immediately improves a team you can already build.

The timing also matters. Version 3.1 launches with Remielle available throughout the patch and Sigrid later, while reruns give additional ways to fill account gaps. If the selector does not force an immediate claim, the most efficient plan is to test Remielle first and see your early pulls before locking in the free S-Rank. If the selector must be claimed quickly, make the decision from your current roster, not from hoped-for banner outcomes. A free S-Rank plus signature W-Engine can stabilize an account for months, but only if it supports the squads you actually use.

Five costumes are coming, but only Lucy’s swimsuit is event-earned

Version 3.1’s summer costume set is split between event rewards and shop purchases. Siliconera reports five costumes tied to the update. Remielle gets the swimsuit Seashade Pas Seul, Sigrid gets Majestic Wavechaser, Vivian gets Iris of the Shore, Lucy gets Princess on Holiday, and Remielle also gets a Moonlight Whispers gown with veiled and unveiled options. According to Siliconera, Lucy’s Princess on Holiday is the only one of these that can be earned through the Summer Waves Roll In event; the others must be bought from the shop. Remielle’s gown can be purchased alone or in a bundle with her swimsuit.

For players budgeting real money, that distinction is the whole story. The sources do not provide prices, bundle discounts, currency costs, or regional store details. Until HoYoverse posts the in-game shop listings, the only confirmed guidance is availability type: Lucy’s outfit is tied to event completion, while the other named costumes are paid shop items.

Cosmetics also intersect with banner planning in a subtle way. Remielle receives two paid looks in the same update that introduces her as a playable Agent. Players interested in both gameplay and cosmetics should separate those budgets early. Pull currency and costume spending are different decisions, and the sources do not state that buying a Remielle costume grants the Agent. Likewise, an earned Lucy outfit is a strong reason to complete the summer event even if you are skipping paid costumes or banners.

The ZZZ July 29 update also extends outside the game through Operation Yum, a restaurant collaboration reported by Siliconera. HoYoverse announced that the event will run worldwide during August 2026, with some regions beginning at the end of July. Confirmed digital rewards include a Crispyboo avatar and namecard, stamina and upgrade items, Senior Investigator Logs, and Dennies across the listed bundles. Siliconera reports regional partners such as Kyuramen in the United States and Wendy’s First Kitchen in Japan, but the exact purchase requirements vary by region and some locations were still awaiting details in the report.

Operation Bagel and story content give returning players homework before July 29

Version 3.1 continues the current story arc under the title “The Long Goodbye.” MMOBomb reports that major factions gather in one place and that the Proxies encounter an old friend tied to a past incident involving uncontrolled powers and a friend’s death. DayOne’s report, drawing from HoYoverse’s announcement, identifies that old friend as Truvia, the heiress of High Ambitions Corp., and says Remielle returns to the spotlight from an En-Nah Gang hideout while the Enchainer comes into focus.

That setup matters because Version 3.1 appears to be asking players to engage with ongoing lore, not only collect anniversary rewards. If you have been away from Zenless Zone Zero, catching up on the latest main story before July 29 should be a higher priority than pre-farming for characters whose final material needs are not provided in the supplied sources. The story context is especially relevant for Remielle, who Siliconera notes has appeared in the campaign before, and for Sigrid, who is introduced through the Airspace Patrol side of the new chapter.

The new permanent mode, Enigma of the Labyrinth: Operation Bagel, is another reason to clean up your weekly routine. Siliconera says the mode arrives at launch, while MMOBomb reports that it sends players into a corrupted area to rescue Eous, is seasonal, and shares weekly progress with Hollow Zero. GamersHeroes also identifies it as a new permanent gameplay mode, though its article spells the title as “Operation Bage,” which appears to conflict with the “Operation Bagel” spelling used by Siliconera and MMOBomb. Players should expect the in-game client to settle the name.

Shared weekly progress with Hollow Zero, as reported by MMOBomb, is the important systems detail. If accurate, Operation Bagel may reduce weekly friction rather than add an entirely separate checklist. For completion-focused players, the pre-patch move is simple: finish current limited events, avoid leaving weekly progression until maintenance, and make sure your Hollow Zero-ready teams are updated. New permanent content tends to reward roster depth, and Version 3.1 is simultaneously handing out a selector that can strengthen that depth.

What to prioritize before the Zenless Zone Zero July 29 update

The cleanest pre-patch plan starts with restraint. Do not spend premium currency solely because Version 3.1 has multiple attractive banners. The confirmed schedule gives players time: Remielle runs throughout the version, Sigrid lands in the second half, and second-half reruns include a selectable rate-up channel according to MMOBomb. That structure rewards waiting for trials, final kit text, and early community testing before committing.

First, decide what your account lacks. If you need a flexible Anomaly piece and have multiple built attributes to pair with her, Zenless Zone Zero Remielle deserves close attention because HoYoverse’s reported Lumiflux mechanic is team-responsive. If your account is short on Ice damage, Sigrid is the banner to evaluate later. If a rerun character would complete an existing team, the second-half Exclusive Rescreening channel may be a more controlled use of pulls than chasing a new role you cannot support.

Second, treat the free S-Rank selector as a roster repair tool. The Zenless Zone Zero free S-Rank gift includes the corresponding W-Engine according to multiple reports, which makes it stronger than a character-only giveaway. Prioritize a character-and-engine pair that improves a team immediately. If you are undecided and the game allows you to delay the selection, wait until after your initial Version 3.1 pulls so the selector does not overlap with a lucky banner result.

Third, complete the Summer Waves Roll In event if you care about costumes, because Siliconera reports Lucy’s Princess on Holiday outfit is the only listed 3.1 costume earned through the event. Paid costume buyers should wait for shop pricing and bundle details, especially if considering Remielle’s swimsuit and Moonlight Whispers gown.

Finally, claim time-limited rewards promptly. MMOBomb reports the livestream redemption code ZZZY2ANNIV was valid through July 19, while DayOne noted a 46-hour redemption window at publication, so players reading after that date should not assume it still works. The larger anniversary package, including 1,600 Polychromes and Signal Searches, is tied to Version 3.1 itself in the reports. Zenless Zone Zero 3.1 is available on PS5, Xbox Series X|S, PC, and mobile, with GamersHeroes also reporting an Xbox PC launch with full cross-platform play. For most players, the winning approach is to arrive on July 29 with finished weeklies, a clear selector shortlist, and enough patience to let Remielle’s new attribute prove itself in the live client.
