Next, the newest update for No Man's Sky, is live and it's implemented some big changes to the game. However, more than a few bugs have appeared on the PC version of the update, so Hello Games has created a temporary fix. Logging into the Experimental Branch on No Man's Sky on PC gives players access to a version of Next where Hello Games has already implemented patches to address crashes and bugs.

To opt into the Experimental Branch, right-click on No Man's Sky from the Steam library page. Select "properties" and then click on the "betas" tab. In the dropdown menu, scroll over "Select the beta you would like to opt into" and then select "Code: 3experimental" when it appears. Opting into the Experimental Branch of Next is completely optional, and you can continue to play in the main version of the game--or switch back and forth--if you want.
