By early 2026, the afterimage of Genshin Impact's Version 'Luna I' update still lingers over the PlayStation community. When the patch went live on September 10, 2025, after a five-hour maintenance window from 06:00 to 11:00 (UTC+8), it delivered far more than routine content. It quietly removed the PS4 edition from the PlayStation Store and pulled a well-worn flag from the mountain summit as the expedition moved to higher camps—a deliberate signpost in HoYoverse's platform evolution. For Travelers still charting Teyvat, the patch compressed a server blackout, a compensation payout, and a legacy console sunset into a single update cycle.

The maintenance itself functioned like a brief eclipse across Teyvat's digital sky. All platforms went dark for an estimated five hours, with compensation calculated at 60 Primogems per full hour of downtime. Eligible accounts at Adventure Rank 5 or above before 2025-09-10 06:00 (UTC+8) received 300 Primogems via in-game mail. The claim window remained open for 30 days after maintenance; unclaimed rewards could not be reissued. A compact timeline of the patch-day sequence follows:

Phase Time (UTC+8) Key Details
Maintenance 06:00–11:00 All servers down; 60 Primogems/hour, capped at 300
Update Live Est. 11:00 Version 'Luna I' playable, PS4 delisting effective
Compensation Within 5h post-update In-game mail for AR5+; 30-day claim window

On the PlayStation front, the delisting of the PS4 edition represented the update's largest structural change. New downloads closed once the patch deployed, but existing installations remained functional and continued to receive updates after the patch. That decision was not an abrupt severance; it operated more like a lighthouse dimming rather than a bridge collapsing. Veterans could keep sailing, but new players were steered toward PlayStation 5, PC, mobile, or Xbox Series X|S. The implication was unmistakable: the long-term roadmap now favors newer-generation hardware and cross-platform play. For legacy account holders, careful backup and platform transfer planning became essential before any future sunsetting accelerates.

Pre-installation had been active across mobile, PC, PlayStation (PS4/PS5), and, for the first time, Xbox Series X|S. HoYoverse urged players to rely on Wi-Fi connections, particularly on mobile plans with data caps, and to clear storage before downloading. Pre-loading reduced patch-day friction but did not open the servers early—players still had to wait for the 11:00 UTC+8 estimate.

Before servers went dark, the practical checklist included several steps:

✅ Complete daily commissions for maximum experience and resin use

✅ Confirm Adventure Rank 5 or higher to qualify for compensation

✅ Pre-download the update package via Wi-Fi

✅ Clear device storage if needed

✅ For PS4 owners, verify continued access and consider backup options

The update also coincided with refreshed minimum and recommended specifications. While not presented as an immediate kill switch for older devices, the changing requirements acted as a slow tide eroding the shoreline; legacy mobile phones and PS4 consoles were expected to face performance declines as Teyvat's features and cross-play ambitions expand. Players with hardware compatibility concerns were advised to check the official update notes after deployment.

At the time of the patch, HoYoverse had not published detailed character or banner lineups for 'Luna I.' Companion updates and banner phases were expected to appear by 2025-09-10 07:00 (UTC+8), but rates, phase durations, and Epitome Invocation details remained unconfirmed before publication. Speculation circulated around future units—such as Aino, a genius mechanic, and Nefer, a rumored 5-star Dendro DPS for a later patch—but nothing in the official materials locked those rotations into place. For Primogem planning, this uncertainty demanded patience rather than impulse.

For Genshin Impact, 'Luna I' was more than the next patch—it was a signpost in live-service evolution. The PS4 transition showed how technical lifecycles now shape player journeys as directly as banner schedules or artifact RNG. By 2026, the trajectory has become even clearer: cross-platform continuity matters more than console lineage, and players who treat platform transitions as part of the gacha landscape will be better positioned for future expansions. Logging in after maintenance, claiming compensation promptly, confirming PS4 access, and watching official bulletins remained the core post-update moves. Teyvat keeps expanding, but the ground beneath it is shifting, one platform sunset at a time.
