HoYoverse, the studio behind hits like Genshin Impact and Honkai: Star Rail, is stepping into new territory with Petit Planet, its first-ever life simulation game.

Building Your Own Petit Planet
At its core, Petit Planet lets players grow and care for their very own planet. Over time, planets expand into galaxies through connections with others scattered across the starry sky. The driving force of this growth is Luca, a unique vitality that shapes landscapes with life and energy.
But what makes the world feel alive are its fuzzy Neighbors. Adorable companions, each with their own dreams, personalities, and stories. By inviting them to settle, sharing gifts, and building bonds, friendships bloom and transform ordinary encounters into unforgettable cosmic moments.

Planting crops and discovering exotic harvests
Fishing, mining, and beachcombing for resources
Cooking and crafting unique items
Designing interiors and exteriors with themed furniture and decorations
Customization goes even deeper, letting players style characters with outfits and reshape environments — even skies, grasslands, and beaches — with Luca’s vitality.
