Starting with Public Test of Update 0.10.5, the authorization system for the test servers will change, and the ability to pre-install new game Updates will be added.
Authorization with the main account
Starting with Public Test of Update 0.10.5, you can use your main World of Warships server (main account) details to log in to the Public Test server. You no longer need to create separate accounts to participate in different tests, and it’s now a lot easier for us to credit your rewards to the Live Server.
To log in to the World of Warships Public Test server using your main account details, select Public Test from the Game Instance section of the Wargaming Game Center, then select the account in the top-left corner.
Rewards for taking part in the Public Test will be credited to the World of Warships Live Server account that you logged in with.
All separate Public Test accounts will be deleted and unavailable for use.
Pre-installation of the Update
Starting with the Public Test of Update 0.10.5, you can download the new game version to your PC in advance and then install it at any convenient time prior to the release. When you’re ready, click the Update button that’s located to the left of the Play button in the Wargaming Game Center once the update files have been downloaded.
To use the pre-install feature, activate preloading for updates in the Updates section of the Wargaming Game Center.
More details on the abovementioned changes, as well as the information about the first round of Public Test of Update 0.10.5, can be found in a dedicated article:
