PetitPetit Planet is HoYoverse's cozy life sim. The public launch date is 4 December 2026 on PC, iOS, and Android, with preload on 1 December.
Five facts I would check first
Global launch is Friday 4 December 2026. Preload opens 1 December 2026. That pair is in the 30 October reveal and in independent write-ups from Saiga NAK and Noisy Pixel.
Play is planned for Windows PC through Epic and the official client, plus iOS and Android. Nintendo Switch 2 has an ESRB Everyone rating and no release date. I found no PlayStation, Xbox, Mac, or Steam product page.
The download is free. ESRB lists in-game purchases that include random items. The game includes a Planet Life Guide chat and AI neighbors in the star market, reported by two hands-on previews.
What you actually do
You keep a tiny planet: build and decorate a house, farm, fish, cook, and meet neighbors. Starsea voyages send you to short islet visits. The Galactic Bazaar is the social hub described in previews. A web build you can play in the browser was not on the official site on 31 October 2026, so the picture above links to the download page.
