The publisher's November 1 announcement confirms these release plans and names the mobile and Epic storefronts. It also announces pre-download starting December 1. The announcement gives calendar dates without a server-opening hour. The original Nintendo Switch has no release plan in this announcement. Publisher announcement

Registration, pre-download and playing

Before December 1, pre-register through the official site or your platform's store. From December 1, check that destination for its pre-download option. Pre-downloading prepares files for launch. Plan to start playing on December 4, subject to the final server-opening announcement.

FOR RETURNING EXPLORERS

A fresh start after Final Beta.

Plan to begin again. The beta’s data wipe does not carry your decorated planet or general progress into launch.

Nalo’s memories had a separate survey-based retention option before the test closed. The notice gives no late survey or general save-recovery route.

Beta closure, Nalo and device-transfer details

The Final Beta ended on October 19, 2026 at 10:00 UTC+8. Its closure notice says test data would be deleted, with a separate survey-based choice to retain Nalo's memories. That option did not promise to transfer a decorated planet, inventory or general progress.

The test guide allowed shared PC/mobile progress within assigned access during the test. That describes movement between devices during that build. For launch preparation, plan around starting again and check any later account-specific entitlement separately.

The closure notice described the Cafe Untamed Feedback Survey before the servers closed. It supplies no post-closure survey route or general planet-recovery procedure. Official closure notice · Final Beta guide

LIFE ON YOUR PLANET

A place to settle in.

HoYoverse describes a life simulator built around developing a planet, planting, decorating and meeting animal-like Neighbors. That puts it close to the home-building and collection interests served by Heartopia.Life. It remains a separate game with its own accounts, progression and currencies.

For a first look, use the official Cozy Cosmos trailer. Its development footage establishes the broad activities. A pre-release trailer cannot establish final unlock levels or recipe costs.

Make room for friends

The Galactic Bazaar is the game’s shared social space. In a November 9 interview, lead game designer Murphy said a personal planet can host seven guests plus its owner. A larger Bazaar is a different type of multiplayer space. The interview does not give a complete launch cross-play or save-transfer policy. Developer interview

Your before-release checklist

Keep the account you pre-register with accessible. Choose your launch platform based on its current official listing. Wait for launch requirements before buying hardware specifically for this game, since a closed-test specification table applies to that test build.

If you previously tested Petit Planet, check the beta-save explanation before expecting a decorated planet to return. If payment systems affect your decision, read the developer statements on cosmetic monetization before relying on an older beta economy guide.

A FEW THINGS TO KNOW

Before you pack.

When does Petit Planet release?

PC, iOS and Android are scheduled for December 4, 2026. Nintendo Switch 2 is planned for 2027.

Can I play as soon as I pre-download?

Pre-download is announced for December 1 and prepares files for the December 4 launch. A precise server-opening hour has not been confirmed in the cited announcement.

Does Final Beta progress carry over?

Final Beta was a data-wipe test. The closure notice described a separate survey option for Nalo’s memories, without promising to transfer general planet progress.
