BODY: Two years after launch, Zenless Zone Zero is finally coming to Steam — and HoYoverse is timing the arrival to one of the game's biggest content drops yet.
In a preview broadcast on October 9, the developer announced that Version 3.3, titled "もう一度、空へと飛び立って" ("Taking Flight Once More"), will go live on October 21. The headline additions are two S-Rank agents, Fionie (フィオニー) and Severian (セヴェリアン), alongside a new mecha-based combat mode that pushes the game further from its original street-brawler roots.
The Steam release is the quieter but arguably more consequential news. Since its June 2024 debut, ZZZ has been confined to HoYoverse's own PC launcher, iOS, Android, and PS5 — a setup that worked fine for players already inside the HoYoverse ecosystem but left the game invisible to the Steam discovery funnel that drives so much PC spending. Genshin Impact made the same move to Steam in 2024; Honkai: Star Rail followed. ZZZ is the last of the trio to arrive.
Also confirmed during the broadcast: a crossover with Honkai: Star Rail. HoYoverse has historically kept its titles in separate narrative boxes, with cross-pollination limited to cosmetic nods and shared composers. A formal collaboration between two of its flagship live-service games marks a shift in how the company is thinking about its portfolio — less a set of parallel products, more a connected roster.
The mecha content, meanwhile, continues a pattern of mode experimentation that has defined ZZZ's post-launch years, as the team has repeatedly reworked the game's exploration layer and combat variety in response to player feedback.
The insider take
Watch the Steam launch date, not the character banners. In Japan, ZZZ has always skewed mobile-heavy — commuter play on the Yamanote Line is the natural habitat for a game built around short, punchy combat loops — while the PC audience that HoYoverse monetizes most effectively sits on Steam, in China and the West. Bundling a Steam debut with an S-Rank double banner and a Star Rail crossover is a coordinated acquisition push, not a coincidence. HoYoverse's Shibuya-adjacent Japan operation has spent two years building ZZZ's local footing through anime tie-ins and Akihabara pop-ups; this is the company betting that the game's second act is on desktop.
