Hello Everyone,

First of all, thanks so much to everyone who has already spent time playing No Man's Sky and letting us know about any issues you've experienced.

Steam users are able to opt-in to the Experimental Branch, where we have pushed a patch to address some problems. We'll be rolling out these fixes to other platforms as soon as possible.

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. Enter "3xperimental" in the textbox and press "CHECK CODE", then select it from the dropdown menu.

As always, thank you to all players who use Experimental and take the time to report any issues you encounter.

Please note there is the possibility that experimental builds 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 on PC: %appdata%\HelloGames\NMS\ and here on mac: ~/Library/Application Support/HelloGames/NMS/

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.

If you decide to opt out of experimental and return to the main branch, we strongly recommend resuming from a backed-up save from the main branch, rather than taking an experimental branch save back to main, which may cause unexpected behaviour.

Feedback and reports of new bugs/issues being found on Experimental are welcome, so please reply to this thread or submit a ticket to https://hellogames.zendesk.com/ with the phrase "Steam Experimental" in the ticket title. If you are running any mods for the game, please list them along with your bug report.
