NEXT Experimental Branch 08/08
Hello everyone,

After the initial round of addressing high priority stability and performance issues, the team have been working intensely on a large number of gameplay fixes and improvements, which we have now finished QA testing and are ready to release to Steam Experimental.

As always, thank you for playing the game and taking the time to report any issues you encounter! We appreciate your patience and understanding while we tackle the highest priority issues first.

Please note that due to the large number of changes in this patch, there is always the possibility it may introduce new issues that haven't been caught in test. We'd like to recommend that all players back up their save files, by making a local copy of the st_[userid] folder found here:
C:\Users\[Username]\AppData\Roaming\HelloGames\NMS\st_[userid])

Note that we don't anticipate any issues here. However, performing your own backups could mean the difference between resuming play immediately, or waiting for the next patch.

Feedback and reports of new bugs/issues being found on Experimental are welcome, so please post them here, or submit a ticket to Zendesk[hellogames.zendesk.com] with the phrase "Steam Experimental 08/08" in the ticket title.

To play in Experimental, right-click on No Man's Sky from the Steam library page and select "Properties". Among the available tabs will be the "BETAS" tab. Select "Code: 3xperimental" in the dropdown menu under "Select the beta you would like to opt into".
