HoYoverse has confirmed that its upcoming life simulation title Petit Planet will enter a closed beta phase on April 21, 2026. The test, referred to as the Stardrift Test, will be accessible to selected players on PC, iOS, and Android platforms.
Sign-ups for the closed beta are currently open, allowing interested players to register for a chance to participate. As with most closed tests, access will be limited, and selected participants will be granted early entry into a curated version of the game designed to evaluate systems, features, and overall stability.
A Shift Toward Life Simulation Gameplay
Petit Planet represents a notable departure from HoYoverse’s previous work, which has largely focused on action-oriented and role-playing experiences such as Genshin Impact and Honkai: Star Rail. Instead of combat-driven mechanics, Petit Planet centers on life simulation systems and player-driven progression within a more relaxed environment.
In the game, players assume the role of a Planet Tender, responsible for maintaining and developing their own planet within a broader interconnected galaxy system. The core experience is structured around daily activities, exploration, and social interaction rather than traditional combat loops.
Gameplay Systems and Player Activities
The gameplay in Petit Planet is built around routine activities that support both personal progression and environmental development. Players can engage in tasks such as farming, fishing, cooking, and resource gathering. These systems are complemented by customization options that allow players to decorate their living spaces and shape the appearance of their planet.
Social interaction also plays a central role. Players can meet and build relationships with various in-game neighbours, interacting through activities like sharing meals, dancing, or spending time together in communal spaces. These relationships are designed to influence gameplay outcomes, including changes to the surrounding environment and the unlocking of new areas or features.
Exploration Through Starsea Voyages
Exploration is facilitated through a system known as Starsea Voyages, which allows players to travel between different islets and locations using a Starsea Map. This system is intended to connect various parts of the game world and encourage discovery across multiple environments.
In the Stardrift Test, HoYoverse is introducing enhanced versions of Starsea Voyages, suggesting improvements to navigation, traversal, or overall exploration flow. Players may also bring along neighbours during these voyages, adding a cooperative or companion-based dimension to exploration.
Galactic Bazaar and Social Spaces
The closed beta will also include access to areas such as the Galactic Bazaar, a hub where players can meet new characters and engage in various interactions. These spaces are designed to function as social and activity centers within the broader game structure, supporting both progression and narrative elements.
New neighbours introduced in this test phase are expected to expand the roster of characters players can interact with, further emphasizing the game’s focus on relationship-building and community-driven gameplay.
Development Timeline and Platform Availability
Petit Planet was first trademarked in 2024 before being formally unveiled in September 2025 with a reveal trailer showcasing its cel-shaded visual style and initial character lineup. Since then, development has progressed toward multiple testing phases, with the Stardrift Test marking a key milestone ahead of a wider release.
The game is confirmed for PC and mobile platforms, with additional platform support also under consideration during development. The closed beta will serve as an opportunity to evaluate performance across supported devices while gathering feedback on gameplay systems and user experience. Make sure to check out more:
