HoYoverse’s stylish urban action RPG, Zenless Zone Zero, is finally heading to Steam. While the upcoming Q2 2026 release is great news for keeping libraries consolidated, players eager to tackle the Hollows on the go with a Steam Deck won’t get a perfectly optimized handheld experience at launch.
Zenless on Steam: A Game Changer for Deck Players?
The arrival of ZZZ on Steam is a significant quality-of-life improvement for handheld PC gamers. Installing the game, which currently requires either the Epic Games Store or the proprietary HoYoPlay launcher, involves extra steps and workarounds on the Steam Deck. A native Steam version means direct installation from your library, seamless updates, and potentially better integration with Steam Input and the Deck’s quick access menu. This simplification alone is a major win for accessibility.
Despite the lack of dedicated optimization, the game has a proven track record of running well on Valve’s hardware with the correct settings. Community guides and performance tests from creators like Deck Wizard show that by adjusting graphical presets and leveraging Proton, players can achieve a stable and enjoyable frame rate. The Steam launch essentially removes the biggest existing barrier: the awkward installation process.
HoYoKProtect and the Proton Bridge
The primary technical hurdle for Zenless Zone Zero on the Steam Deck isn’t raw performance, but compatibility. The game employs HoYoKProtect, a kernel-level anti-cheat system common to HoYoverse titles. Historically, such software can block operation on Linux-based systems like SteamOS. However, thanks to the incredible work on Valve’s Proton compatibility layer, ZZZ has run on the Deck since its original release.
This reliance on Proton means the game lacks native Linux support and is unlikely to receive the coveted “Steam Deck Verified” badge at launch. The developers’ statement that players are “welcome” to run it on Deck is an acknowledgment of this community-driven reality rather than a promise of official support. For players encountering issues, third-party tools like the unofficial “Sleepy Launcher” have become essential community patches to smooth over Proton-related hiccups.
The Waiting Game for True Steam Deck Optimization
According to a report from RPG Site, the development team confirmed that no specific Steam Deck optimization patches are planned to coincide with the Steam release. This means players shouldn’t expect tailored graphical presets, perfect controller glyphs, or system-level tweaks for the Deck’s APU on day one. The experience will largely mirror the current one: functional but requiring manual configuration.
There is a silver lining, however. The developers noted they would be reviewing player feedback from the Steam platform, which inherently has a large Deck-owning user base. This influx of data and community reports from a centralized platform could finally give HoYoverse the impetus to invest in proper handheld optimization in a future update. For now, the path to playing is clearer, but the journey to a flawless portable experience continues.
