Closed Beta Testing Timeline
To maintain transparency regarding where game mechanics and data originate, our editorial team maintains a strict chronology of closed playtest phases:
1. First Light Playtest (Early 2024)
An ultra-small, invite-only technical test conducted under strict non-disclosure. Focused strictly on fundamental spherical geometry rendering and client-side physics stability.
2. Habitable Test (October 2024)
The first major closed beta test with active gameplay streaming permitted. This phase introduced:
- Initial spherical terraforming tools and river redirection mechanics.
- First resident invitations (Esassani, Zephyr, and Miandoli).
- Core farming rotations, cooking sprites, and Loomix vending machine daily stipend loops.
3. Starsea Voyage Test (2025)
Expanded testing phase focused on mid-game content and multiplayer infrastructure:
- Celestial explorer vessel mechanics and navigation across the Starsea ocean.
- First public stress testing of the Galactic Bazaar multiplayer hub.
- Hardware optimization passes addressing memory utilization on iOS and Android devices.
4. Current Phase: The "Coziness Test" (2026)
The official global playtest recruiting players directly through the newly launched planet.hoyoverse.com portal.
