In late 2023, HoYoverse opened the application window for Zenless Zone Zero's Equalizing Test. In 2026, the game has already launched and evolved well beyond that early development build. Even so, the original test announcement still gives a clear picture of how the studio handled beta access, device compatibility, and player eligibility. It might not be a current sign-up, but it remains a useful reference for anyone following the game's history or comparing early requirements with the final release.

The Equalizing Test was described as a limited-account beta with no payment options and full data deletion. Players could join on PC, Android, and iOS. Because the game was still in development, HoYoverse made it clear that everything seen during the test, from character skills to art presentation, did not represent the final quality. That caveat was important for early testers who might have expected a polished experience.

Sign-ups started on November 4, 2023 at 12:00 UTC+8. The deadline was not fixed at that point. HoYoverse said more official announcements would follow. To enter, players had to go to the official sign-up page, click the SIGN UP NOW button, log into a HoYoverse account, and enter device details. That step completed pre-registration. After that, they also had to fill out the Equalizing Test sign-up survey. Only players who finished both steps could win a qualification. Completing just one requirement was not enough. That was a key detail many people missed.

There was also an age restriction 🔞. The test was only open to users aged 16 and above. Anyone below that age could not receive a test qualification. HoYoverse also warned players to fill out the survey truthfully. Inaccurate information would lead to exclusion from the test. Those rules made the selection process a little stricter than a typical open beta.

When the sign-up window closed, HoYoverse notified successful players by email 📧. Because of that, entering a correct email address during pre-registration was essential. There was also a Test Qualification Query Page announced after the sign-up deadline. Players could check their status there instead of waiting only for an email. It gave everyone a second way to confirm whether they had made it in.

Device requirements were split into recommended and minimum tiers 📱. HoYoverse was still working on compatibility with different devices, so the list was not final. The recommended specifications are summarized below.

Platform	Recommended Specs
PC	10th Gen Intel Core i7, 8GB RAM, Nvidia GeForce GTX1660
iOS	iPhone 11 Pro; iPad with A13 chip, 4GB RAM; Mac unsupported
Android	Snapdragon 8 Gen 1, Dimensity 8200, or Kirin 9000, 8GB RAM

The minimum specifications were also listed separately.

Platform	Minimum Specs
PC	7th Gen Intel Core i5, 8GB RAM, Nvidia GeForce GTX970
iOS	iPhone XS; iPad A12, 4GB RAM; Mac unsupported
Android	Snapdragon 888, Dimensity 1200, or Kirin 990, 8GB RAM

System requirements were fairly straightforward. Windows needed Windows 10 or later. iOS needed iOS 14.0 or later. Android required Android 11.0 or later. On top of that, players needed enough free storage. The PC version demanded at least 40GB. iOS required at least 17GB, and Android required at least 15GB. Those storage numbers were significant, especially for mobile players who had to clear space before the test.

There were also a few other ways to qualify 🎟️. Watching the Equalizing Test teaser and joining the HoYoLAB discussion event gave players a chance to get in. Two web events, A Sandwich-Scented Dream and ZZZ Sign-Up Draw Event, offered test qualifications and merchandise prizes through tasks. HoYoverse encouraged players to keep an eye on HoYoLAB for more qualification events. These side activities gave people more than one shot at access, which was a nice touch.

The fine print included several important warnings ⚠️. All test content was not final. If a player qualified, the installation guide email matched the platform selected during sign-up. If multiple platforms were chosen, HoYoverse could randomly pick one. Test qualification was linked to the first login device. Players could use one device each for PC, iOS, and Android. Changing devices during the test would lead to a ban, with no unbanning possible during that phase. This rule was especially strict and caught some players off guard. HoYoverse also reminded everyone not to trust account sharing or trading offers. Test qualification could not be transferred or sold. Unauthorized use of the test client or account would result in qualification being revoked. Finally, each HoYoverse ID could receive only one test qualification across all related events.

Looking back from 2026, those early beta rules reflected a focused testing phase. The game has since changed in many ways, with new characters, systems, and platform support. But the Equalizing Test sign-up details still show how HoYoverse managed expectations and protected test accounts during a crucial pre-launch period.
