| Zenless Zone Zero Version 2.8 launches today with new S-Rank agent Promeia and confirmation that the game is heading to Steam in Q2 2026. |
HoYoverse closes out Season 2 with two new S-Rank agents, a fresh combat mechanic, and a long-awaited Steam release window – plus a first look at an unusually stacked Season 3 roster.
If you’ve been counting down the minutes until Zenless Zone Zero’s next major story beat, the wait is finally over. Version 2.8, officially titled New: Eridan Sunset, launched today on mobile, PC, PS5, and Xbox Series X/S, bringing the curtain down on Season 2 with one of the most content-packed updates the urban-action RPG has seen since launch.
But the headlines don’t stop at new characters and story missions. During the 2.8 special program livestream, HoYoverse dropped a bombshell that PC players have been asking about for nearly a year: Zenless Zone Zero is coming to Steam. The store page is already live, and depending on how many players smash that Wishlist button, everyone could be walking away with free Polychromes.

Steam Version Confirmed – And It Comes With a Catch-Up Mechanic for Your Wallet
Let’s start with the news that’s been swirling across every ZZZ community feed since the livestream aired. Zenless Zone Zero is officially heading to Steam – something HoYoverse has been notably quiet about despite the game’s massive success on other storefronts.
The Steam version is targeting a Q2 2026 launch window, which puts it right around the Version 3.0 update in June. That’s about eight months from now, so don’t expect to migrate your dailies over tomorrow. But here’s the critical detail for anyone worried about starting over: progress and purchases carry over. You’ll log in with your existing HoYoverse account, and everything – your agents, your Polychromes, that S-Rank engine you grinded two weeks for – comes with you.
This makes Zenless Zone Zero only the second HoYoverse title to hit Steam, following Honkai Impact 3rd back in October 2021. Notably absent from that list are Genshin Impact and Honkai: Star Rail, both of which remain exclusive to the company’s own launcher, the Epic Games Store, and mobile app stores. Whether this signals a broader shift in HoYoverse’s PC distribution strategy is anyone’s guess, but for ZZZ players who prefer Steam’s infrastructure (achievements, playtime tracking, Steam Deck compatibility), it’s a welcome surprise.
Wishlist Milestone Event – Free Polychromes for Doing Almost Nothing
To sweeten the announcement, HoYoverse launched a Wishlist Milestone Event tied directly to the Steam store page. As the total number of Wishlists crosses set thresholds, every player – regardless of whether they personally Wishlisted the game – will receive in-game rewards. The tiers haven’t been fully detailed yet, but expect Polychrome bundles, Denny packs, and possibly even Master Tapes at the highest milestone.
It’s a clever move. HoYoverse gets a massive day-one launch boost on Steam metrics, and players get free currency for what essentially amounts to telling their friends to click a button. The store page is already live, so if you want to contribute, searching “Zenless Zone Zero” on Steam will get you there.
Version 2.8 Story: Chasing Ramiel Through the Outer Ring
Of course, the Steam announcement isn’t the only reason to log in today. Version 2.8 wraps up the New Eridu storyline that’s been running through the back half of Season 2, and the pieces are finally coming together.
The plot picks up with multiple factions converging on the Outer Ring – that desolate, lawless zone outside the city’s protective walls. They’re all chasing a mysterious figure named Ramiel, whose motives and abilities have remained frustratingly vague through the last few updates. That changes in 2.8.
Joining the hunt as intelligence contacts are Promeia, described as “the executioner of Krampus,” alongside Starlight Billy and Cissia. If that name sounds familiar – yes, Starlight Billy is a heavily upgraded version of the Billy Kid that’s been riding shotgun in your roster since the game’s prologue. HoYoverse isn’t just giving him a new coat of paint; this is a full mechanical rework that positions him as a top-tier damage dealer.
Without diving into heavy spoilers, the 2.8 story arc sets the stage for Season 3 in a way that feels earned. Ramiel isn’t just a villain-of-the-week; the revelations about their connection to New Eridu’s past reshape how you’ll look at several key characters moving forward.
Two New S-Rank Agents: Promeia and Starlight Billy
The banner schedule for Version 2.8 splits cleanly into two phases, each introducing one new S-Rank agent alongside a rerun of a fan-favorite.
Phase 1 (Now through May 27): Promeia + Lucia Rerun
Promeia is the headline act for the first half of 2.8, and she’s bringing something entirely new to the meta: an Ice Anomaly unit. Until now, the Anomaly archetype has been dominated by Physical, Fire, and Electric agents. Ice gets its first real representative in this role, and early impressions from creator server testers suggest Promeia’s anomaly buildup rate is aggressive enough to shift team compositions around her.
She’s a close-to-mid-range fighter who applies Frostbite stacks faster than any existing Ice agent. Her EX Special generates a frost field that slows enemies and amplifies anomaly damage for the whole party. If you’ve been running Ellen as your primary Ice DPS, Promeia offers a different playstyle – less about raw crit damage and more about triggering Disorder reactions on cooldown.
Running alongside Promeia is a Lucia rerun. Lucia (Fire Stun) remains one of the most versatile stun units in the game, and if you missed her first banner, this is your best shot to grab her before Season 3 shifts the meta.
Phase 2 (May 27 through June 16): Starlight Billy + Orphie Rerun
Starlight Billy is the agent that’s got longtime players buzzing. The base Billy character – a Physical Attack agent with a chaingun and a love for cheesy action movies – has been a meme-tier unit for most of the game’s lifespan. Usable, but never optimal. Starlight Billy throws that reputation out the window.
He’s a Physical Rupture agent, which is a completely new damage type. Rupture acts as a delayed burst: you build stacks on an enemy, then trigger the effect to detonate all stacks at once. It rewards careful rotations and punishes button-mashing. Billy’s chaingun is still there, but now each hit applies Rupture stacks, and his ultimate detonates every stack on the field simultaneously. In coordinated team play, the number is going to be silly.
The Orphie rerun (Ether Support) rounds out Phase 2. Orphie has quietly been one of the best support units in the game, providing energy generation and damage buffs that scale with the team’s anomaly proficiency. If you’re planning to build around Promeia or Starlight Billy, Orphie is a natural fit.
New Combat Systems: Vortex Mechanic and Attribute Enemies
Beyond the agents, Version 2.8 introduces two significant combat additions that will matter long after this update’s banners expire.
Vortex is a new combat mechanic that creates persistent field hazards. When certain abilities or enemy attacks trigger a Vortex, it pulls nearby enemies toward its center and deals repeated damage over time. Several of the new endgame encounters in 2.8 are designed around Vortex positioning – forcing you to decide whether to fight inside the pull zone or waste time dodging out of it.
The update also adds a new attribute enemy type (currently unnamed in the patch notes, dataminers are calling it “Void-touched”). These enemies resist standard anomaly effects but take bonus damage from Rupture – which, conveniently, is exactly what Starlight Billy deals. It’s a soft push toward pulling for the new units, but existing Physical and Ice teams can still clear with optimized rotations.
The Eridan Sunset limited event runs throughout the 2.8 patch, offering Polychromes, upgrade materials, and a free W-Engine for players who complete its story chapters. Expect it to take about two to three hours total if you’re just clearing for rewards, longer if you’re reading all the dialogue.
Season 3 Tease: Void Hunter Faction and Wind Anomaly
Here’s where community attention is starting to fracture. HoYoverse used the 2.8 livestream to do something they almost never do: release drip marketing for multiple Season 3 agents at once, rather than the usual week-by-week reveals.
The result is a stacked lineup that has players openly debating whether to pull for Promeia now or hoard every Polychrome until June. Season 3 is shaping up to include:
- A new Wind Anomaly archetype – the first time Wind damage gets the Anomaly treatment. Datamined ability descriptions suggest a focus on swift, multi-hit combos that stack a unique DoT effect.
- The first agents from the Void Hunter faction – this is a huge deal. Void Hunters have been name-dropped in lore entries since Version 1.0, but no playable characters have carried the tag until now. Expect unique mechanics and higher-than-average base stats.
- At least three S-Rank agents in the first two patches of Season 3, based on the silhouette teaser shown during the livestream.
If you’re a free-to-play or light-spending player, the smart money is on waiting for Season 3 previews before committing to Promeia’s banner. But if you love Ice teams or just want to play with the new Vortex mechanic immediately, she’s a strong pull.
Xbox Mode on Windows 11 – A Console-Like Experience for PC Players
One final note for PC players who prefer controllers and couch gaming. This week, Microsoft rolled out an optional Windows 11 update ( KB5083631 ) that enables a full Xbox mode for Windows PCs. It’s essentially the Xbox dashboard interface, designed for controller navigation, and it launches directly into a full-screen, console-style environment.
Zenless Zone Zero isn’t officially “optimized” for Xbox mode yet, but early testing shows it runs without issue. You can launch it from the Xbox app, navigate menus with a controller, and never touch a mouse or keyboard. It’s a niche feature, but for anyone who’s been frustrated by Windows’ half-hearted big-picture modes over the years, it’s worth installing the optional update.
The Bottom Line
Version 2.8 is a turning point for Zenless Zone Zero. It closes one story arc, opens another, and finally answers the Steam question that PC players have been asking since day one. The new agents are interesting (especially Starlight Billy’s Rupture mechanics), the Vortex system adds legitimate tactical depth, and the Season 3 teaser suggests HoYoverse is ready to start moving away from the launch-era agent designs toward more experimental kits.
If you’ve been on the fence about jumping back in, now’s the time. The Steam Wishlist event means free pulls for everyone regardless of where you play, and the 2.8 story is reportedly some of the strongest writing the game has seen.
Zenless Zone Zero Version 2.8 “New: Eridan Sunset” is available now as a free download on iOS, Android, PC (HoYoverse launcher and Epic Games Store), PS5, and Xbox Series X/S. The Steam version launches in Q2 2026.
