HoYoverse released a vibrant trailer for its upcoming title Petit Planet, finally revealing the worldwide launch date – December 4, 2026. The official announcement rang out during the Opening Night Live at Gamescom 2026, and a music video titled Ba Ba La Ba ~ Petit Planet Stretch dropped on September 20.

The game is a cross‑platform life simulation where each player builds a tiny personal planet. Players can garden, decorate, care for fluffy critters, and explore colorful zones at a fully meditative pace. The focus is on comfort and zero stress, while social tools let friends visit, team up for mini‑games, and gather resources together.

Registration for the closed beta, dubbed Stardrift Test, is now open on PC, iOS, and Android. Early testers will help shape the final experience, and the community is already gearing up for shared adventures in this whimsical world.
