HoYoverse reveals details for new life simulation game Petit Planet

HoYoverse, the developer behind Genshin Impact and Honkai: Star Rail, has shared new details regarding its upcoming life simulation game, Petit Planet. Scheduled for release on December 4, 2026, for Android, iOS, and PC, the title marks the company’s first venture into the slow-life genre.

During a recent media tour in Seoul, lead game designer Murphy and lead artist Yinli discussed the game’s core mechanics and inspirations. While the developers acknowledged the influence of the Animal Crossing series, they highlighted several unique features, including a setting on uninhabited planets, a social system called the Star Market for player interaction, and AI-driven NPCs with memory systems that react to player behavior.

The game is designed as a live-service title, aiming to provide long-term community growth through seasonal events. Developers emphasized a commitment to a relaxed pace, stating they aim to minimize the pressure of daily tasks to maintain a cozy experience. A version for Nintendo Switch 2 is also being considered as a strategic goal.
