Petit Planet: Game Overview, Release Date and Gameplay

Petit Planet is an upcoming free-to-play cosmic life simulation game developed and published by HoYoverse. You tend a small planet, grow food, decorate a home, meet animal neighbors and sail through a region called the Starsea. It launches globally on December 4, 2026 for PC (Windows), iOS and Android.

What is Petit Planet?

Petit Planet is HoYoverse’s take on the cozy life sim. Instead of a fixed village, you get a small planet of your own and a whole sky of other places to visit. The game is built around slow, real-time progress: crops take time to grow, shops rotate daily, and neighbors remember whether you showed up with a gift they actually like.

The official tagline is “Meet Where the Stars Bloom.” The Chinese name is 星布谷地 (Xīng bùgǔ dì); the Japanese name is プチプラネット and the Korean name is 쁘띠플래닛. Outside China, the publisher is HoYoverse, the global brand of miHoYo’s subsidiary Cognosphere.

What you actually do

Neighbors and bond

Seventeen neighbors are known in the Final Beta data. Five are base neighbors who settle through the main story and do not use neighbor capacity: Mobai, Elsasani, Glenn, Mors and Trixie. The other twelve are invite neighbors with bond profiles, loved gifts and a house.

Inviting a neighbor is a two-encounter process. You first meet them on a specific encounter islet during a Starsea Voyage. After the second meeting they can visit your planet, complete a short quest, and ask to settle if you have capacity. Once they move in, chatting, gifting and dinners raise bond; higher bond levels unlock talents and Homi Decor requests.

Open the full neighbor database for gifts, talents, houses and encounter locations.

The Starsea and its galaxies

The Starsea is the space between planets. Voyages take you to islets in different galaxies, each with its own terrain, climate and creature pool. Four galaxies are known: Hexia (verdant plains), Taffeh (golden prairies), Norvan and Pashah. Official terrain details for the latter two are still limited.

Progression without a combat grind

The main progression tree is the Luca Arbor, a 40-level planet tree. Upgrading it costs Luca and Lucasprout, and each level adds farm plots, Luca Fruit slots, neighbor capacity, weather, new terrain or a cosmetic biome. In the Final Beta it cost 960 Luca to fully upgrade; individual level costs range from 20 to 50 Luca and 10 to 60 Lucasprout.

Around that spine sit several soft goals: house rating, Omni-Gallery collection, Folio Score tiers, neighbor bond levels and the daily Footprint checklist. Dough is the everyday spending currency; Footprint and Miraprint are earned through tasks and spent at Loomix Mart and Curio Emporium.

Social features and cross-save

Petit Planet is marketed around social features. Players can visit other Planet Tenders’ planets, and the Final Beta included privacy controls for visits. The official beta FAQ also confirms that, with the same HoYoverse account, game data carries over between PC and mobile.

What is not confirmed: the exact launch-day multiplayer feature set, whether every social activity is available at launch, and whether cross-play is limited by region or platform. We keep those questions open rather than guessing. See the multiplayer guide for the confirmed/reported split.

Release date, platforms and price

The PC release is available through HoYoPlay and the Epic Games Store; iOS and Android pre-registration are open on the App Store and Google Play. See platforms and release date for the full breakdown.

Beta history and data status

The Final Beta was a limited-access, data-wipe test with no in-game purchases. All test progress was deleted when the servers closed. That means every screenshot, tier list and database value from the beta is a snapshot, not a guarantee of launch balance.
