About Prior Release of the latest version

Buriedbornes2 will distribute pre-releases prior to update releases as needed to ensure a more stable release.

What is “Prior Release”?

This is a test version that allows you to play the latest version, which will be delivered next, prior to the full release.

This is open to all participants who meet the following participation requirements.

When the latest content is delivered, you can be the first to access it, but it may be unstable.

In some cases, we may also deliver to players who are unable to play due to an unprogressive problem, with the goal of delivering a playable environment to them as soon as possible.

Participation Requirements/Precautions

  • You have to read this entire article on your own, understand and agree with its contents.
    • Please do not give the URL for participation directly to other prospective participants.
      We may not be able to support to participants who have not read this page, even if a problem arises.
  • You have to help us find problems.
  • You have to report problems to the developer when they occur.
  • If you identify any problems, you have to submit a bug report.
    • Touch the clock at the top of the game screen to open the device info screen.
      Bug reports can be submitted from this screen.
  • You have to stop playing immediately when you found that there is a critical problem.
  • You have to follow instructions when given by the developer.
  • You have to confirm the latest information about the prior release by the official website, Discord, etc.
  • You have to accept the risk of save data rollback and other risks.
    • If you do not have it yet, please publish your backup code and keep it at hand.
    • If you already have backup codes, please upload your latest save to the game server immediately before entering Prior release.
    • When reverting back to the current version after participating in a prior release of a major version upgrade, there may be instances where saved data is not compatible and does not function properly. In such cases, please contact us directly to discuss backup and restore procedures for saved data.
  • [iOS Version Only] While using the pre-release version, various items cannot be purchased and purchased supporter plans will not be reflected. This is because iOS TestFlight refers to the sandbox purchase function (the production purchase function is not referred to).

How to leave from the Prior Release

Then re-download the latest version if necessary.


Go to the Buriedbornes2 game page in the AppStore and download the latest version.

(Even if it is the same version as the TestFlight version, the download button should appear.)

If you have already downloaded the latest version, you can continue playing, but if the app downloaded via TestFlight is still installed, it may not automatically download via AppStore when the next version is delivered.

Steam PC

Open Buriedbornes2 properties, select the Beta tab and choose “None”.

If necessary, the game client will be added to your download list and you will be asked to re-download it.


Will the progress made in the prior release carry over to the Production release?

Yes, you use the same data as in the Production release.

When will the Prior Release be distributed?

In the future, it will be delivered 1-2 days before the Production release. (For major updates, we will distribute about 1-2 weeks in advance and take a slightly longer prior release period.)

If no major degradation (problem recurrence or another problem) is confirmed in the prior release, we will proceed with this release.

If a degradation is confirmed, this release may be postponed.
