Revision 1

Overview

The Stardrift Test was the second closed beta for Petit Planet. It started on April 21, 2026, and ran on PC, Android, and iOS. The test added significant content over the earlier Coziness Test, including a live multiplayer social hub, an off-planet travel system, and an expanded neighbor roster.

Dates and Platforms

The Stardrift Test started on April 21, 2026. Where the first closed beta was limited to PC and iOS, the Stardrift Test added Android, making it the first build playable on all three of the game's announced platforms (PC, iOS, Android). The exact end date was not announced as a single fixed cutoff; the test ran for a stretch of weeks with rolling sign-ups.

New Content vs the First Test

The Stardrift Test introduced several systems that were not present or were significantly less developed in the Coziness Test:

Sign-Ups and Access

Sign-ups ran through the official Petit Planet site and the HoYoverse community channels. Selected players received access to the test client on their chosen platform. Like most HoYoverse closed betas, NDAs were not strictly enforced and players were able to share gameplay footage and previews freely, though the developers asked for context-sensitive sharing of unfinished content.

Press and Hands-On Coverage

The Stardrift Test was the first build with substantial outside press coverage. Hands-on previews appeared from multiple gaming outlets and content creators in the days following the test start date. The previews focused on the new social hub, the Planet Maker upgrades, and the expanded Neighbor friendship loops, with most coverage framing the build as a meaningful step beyond the cozy-but-small Coziness Test.

Notable Confirmations

Multiple features were explicitly confirmed in the Stardrift Test build that had been speculated or hinted at before:

Cross-platform play with shared saves between PC and mobile.

No combat in the playable build; progression comes through Farming, Fishing, Mining and Crafting, and Neighbor friendship.

Real-time clock synchronized with HoYoverse servers (preventing time manipulation for daily resets).

No inventory limit, a notable quality-of-life choice.

No gacha system in the test build; the final monetization model has not been confirmed.

Position in the Beta Roadmap

The Stardrift Test followed the Coziness Test (November 7 to December 1, 2025) and represents the second major closed-beta phase. A separate long-term playtest called the Staycation Program is also ongoing as a small-scale, confidential testing effort. No official release date for Petit Planet was announced at the time of the Stardrift Test.
