HoYoverse has announced that Petit Planet, its free to play cosmic life simulation title, will launch globally on December 4, 2026. The cozy galactic life sim arrives as a free download across PC through the Epic Games Store and a direct client, plus mobile on iOS and Android, according to the Gematsu report on the release date announcement. Players can start preparing early, since pre-downloads open on December 1 and pre-registration is already underway on every platform.
Quick facts: Game: Petit Planet, a free to play cosmic life sim from developer miHoYo and publisher HoYoverse. Launch date: December 4, 2026, with pre-downloads from December 1. Platforms: PC via the Epic Games Store and direct client download, iOS via the App Store and Android via Google Play. Core activities: planet shaping, home decorating, farming, fishing, bug catching, beachcombing, cooking and Starsea exploration. Multiplayer hub: the Galactic Bazaar for trading, creating and meeting other Planet Tenders.
Shape a personal planet in the Starsea
Petit Planet hands each player a small world of their own inside the vast Starsea and lets them reshape it from the ground up. Terrain, coastlines and skies can all be molded to taste, and home interiors are fully decorating friendly, so no two planets need to look alike. The fantasy is closer to a cosmic garden plot than a space empire, with the emphasis on a peaceful daily rhythm rather than conquest or competition.
The heart of that rhythm is the cast of fuzzy Neighbors. These charming original characters arrive looking for a home and bring personal storylines with them, and everyday moments such as sharing meals, exchanging gifts and going on quiet strolls deepen the bond over time. Alongside that social layer, the activity list covers farming curious crops, fishing, bug catching, beachcombing and cooking, which gives planet life a steady loop of small goals between decorating sessions.
Starsea voyages and the Galactic Bazaar
Life is not limited to the home planet. Players can set sail across the Starsea with helpers to visit uncharted areas, gather crafting materials and track down rare creatures. The voyages add a light sense of discovery to a genre that can otherwise feel fenced in, since every trip outward is a chance to bring something new back home for the next decorating or crafting project.
For players who want company, the Galactic Bazaar serves as a bustling universe wide hub where Planet Tenders can trade goods, create together and simply hang out. The hub structure keeps multiplayer optional and low pressure, which fits the cozy brief, while still giving friends a shared place to meet outside their own planets. It is the social anchor of a game that is otherwise built around quiet solo progress.
Platforms, pre-download and pre-registration
The release covers PC through the Epic Games Store alongside a direct client download, plus iOS through the App Store and Android through Google Play. Cross platform availability at launch means planet progress is not tied to a single device, an important detail for a daily rhythm game that players will likely check in short bursts on phones and in longer sessions on PC.
Pre-registration is open now on all platforms with in game bonuses for early signups, and pre-downloads unlock on December 1 so players can be ready the moment servers open. The official Petit Planet site carries the latest signup details and a closer look at the world ahead of launch day.
HoYoverse keeps broadening its lineup
Petit Planet lands as HoYoverse continues to stretch well beyond its action RPG roots. The company recently pulled back the curtain on Nodusfall, its upcoming co-op action game, while flagship Genshin Impact 7.2 arrives this November. A relaxed life sim rounds out that slate with something aimed squarely at players who want comfort over combat.
The cozy corner of the calendar is getting crowded in a good way. Fellow life sim Witchbrook is set for late January, which gives genre fans two wholesome launches to look forward to within two months. For players who have been waiting for a low stakes world to tend between bigger releases, December 4 now has a clear marker on it.
