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 Final Beta began September 20, 2026. It is limited to selected participants, has no purchases and wipes progress afterward. Those conditions describe a live beta test 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.
