Confirmed launch window
The official Petit Planet account’s August 26 HoYoLAB announcement states a Winter 2026 launch window. That announcement gives a season rather than a specific calendar date. This page therefore does not convert the window into a guessed month, day or countdown.
September testing is separate
The Epic listing displays December 30, 2026 when checked September 18. We distinguish that storefront date from the seasonal launch announcement: the cited announcement does not independently confirm that exact day. Follow official updates before treating a store date as a guaranteed launch schedule.
The official Final Beta FAQ gives September 20, 2026 as the test start date. Testing is limited to selected participants, has no purchases and wipes progress afterward. Those conditions describe a beta rather than general launch availability.
Read the Final Beta guide for its application deadline and invitation process. If you want to reserve the launch game, follow pre-registration. We update this page when a checked official announcement changes the release information; its modification date records content changes rather than a recurring check.
