What is it

Meet the endless possibilities of life on your own planet

Petit Planet is miHoYo’s first slow-life game. As a Planet Tender you own a small world inside the vast Starsea and shape it from the ground up.

The loop centres on “Luca” vitality: reshape terrain, coastlines and skies, build and decorate your home, then fill your days with farming, fishing, bug catching, beachcombing and cooking — all alongside fuzzy Neighbors, each with their own personality and story.

Life is not limited to your planet. Sail across the Starsea to visit uncharted isles, gather materials and meet new friends, then bring it all back home. Or hang out at the Galactic Bazaar, a universe-wide hub for trading, creating and relaxing with other players.

Cross-platform account sync across PC / iOS / Android; pre-downloads open December 1 and the game is a free download.

Core gameplay

Six quiet joys of planet life

TERRAIN

Planet shaping

Combine skies, meadows and coastlines freely with Luca fruit — grid-free terrain editing with your own lighting and weather. No two planets look alike.

FARM

Farming & ecosystems

Plant curious crops, grow Luca plants, and match crop lineages to climate bands. Fishing and bug catching complete your vivarium.

HOME

Home building

Design furniture and interiors, turn a shed into a castle, dress up the yard with lights and flowerbeds.

NEIGHBORS

Neighbors

16+ fuzzy neighbors each have a job, a personality and a story. Gifts, strolls and shared meals raise bonds — high bonds invite them to move in.

STARSEA

Starsea voyages

Set sail with helpers to uncharted isles: gather crafting materials, track rare creatures, bring surprises home.

BAZAAR

Galactic Bazaar

A universe-wide multiplayer hub to trade, create and hang out — a warm community with no leaderboards.
