Joining a Once Human PTR test server—officially designated as Pioneer Testing—does not require an alternate game client. Players submit their numeric in-game UID through official recruitment questionnaires, sign a binding Non-Disclosure Agreement (NDA), and access the test environment directly through their existing live game client. Character progression inside Pioneer Tests is wiped upon completion, though select milestone rewards such as Wish Emblems transfer to the live server.
How to Apply for Once Human Pioneer Server Access
Developer recruitment for Once Human experimental testing does not run on an open-door policy. Participation relies on curated player selection managed through web-based surveys hosted on platforms like Easebar.
To apply for a testing phase:
- Locate the official survey: The team posts recruitment links through official news bulletins on the Once Human official website.
- Locate your account UID: Open the game and check your HUD or character profile. Copy down your UID, which is a numeric string.
- Complete the questionnaire: Enter your UID, hardware specifications, and gameplay background. Double-check all contact entries.
- Check notification channels: Selected players receive confirmation and server onboarding instructions via email, SMS, in-game mail, or Discord before the server opens.
Selection is capped by platform and region. For example, the Isles of Abyss Final Test established a 4,000-player recruitment ceiling across North America, splitting access into 2,500 PC participants and 1,500 Console participants.

Client Setup and Launching the Test Environment
Unlike traditional public test setups that require a separate, secondary launcher download, Pioneer Tests integrate directly into the standard client.
- PC Users: If accepted, your account credentials are automatically whitelisted. Launching the game via your regular desktop client opens a prompt to enter the Pioneer Test. You can toggle between live scenarios and the test server using the mode switch button located in the upper-left corner of the interface.
- Console Users: Console players must download the full Resource Pack before they can launch the Pioneer Test environment.

Test Rules, NDA Requirements, and Wipes
Pioneer Tests operate as confidential, closed testing environments rather than marketing previews. Every tester must accept an NDA before gaining access to experimental builds.
Under this agreement, players cannot record footage, take screenshots, stream gameplay, or publish reviews on Discord, Reddit, X, YouTube, Twitch, TikTok, or Bilibili. Violations trigger strict penalties, including account bans across linked accounts and potential legal action.

Does Test Server Progress Carry Over?
Character progression—including base structures, gear blueprints, and level progression—does not carry over to live servers. Test servers undergo a complete data wipe once the testing period ends.
However, testing tasks yield account-bound compensation in the form of Wish Emblems. These tokens are distributed directly upon claiming and synchronize with your live server profile. You can spend them in the live version under Events - Shop - Starwish Shop.
Documented reward structures include:
- Daily Sign-ins: 100 Wish Emblems per day across 10 check-in days.
- Cosmetic Milestones: The "Jade Nocturne" cosmetic reward awarded on check-in day 7.
- Progression Milestones: 300 Wish Emblems awarded upon reaching Tech Level 10.
While your test character disappears after the server closes, these accumulated tokens and event unlocks remain permanently on your official account. For standard accounts on live servers, players looking to expand their personal territory aesthetics or battle pass rewards can also explore Once Human options for Crystgin top-ups.
Frequently Asked Questions
Can I play on live servers and the test server at the same time?
You cannot run both simultaneously on one machine, but you can jump between them freely. Use the mode switch button in the upper-left corner of the screen to swap between the Pioneer Test and your standard live scenario without reinstalling files.
What happens if I leak Pioneer Test gameplay?
Sharing test footage, stream feeds, or unreleased mechanics violates the binding NDA. The developer enforces hardware or account-level bans across all associated profiles and reserves the right to pursue formal legal action against leakers.
Where do I spend the rewards earned during Pioneer Testing?
Wish Emblems claimed on the test server synchronize with your official live account. Access the Events tab, navigate to Shop, and open the Starwish Shop on your standard server to redeem them.
