No Man’s Sky: How to Get All Endings

True Atlas

You can go the opposite route with Atlas as well and choose to follow this unknown entity to the very end. In order to get the actual Atlas ending, though, you need to do two very important things. The first is that you need to save all of the Atlas Stones that you obtain from each of your visits. You need 10 during the last stage to trigger the real ending. The second is to continue raising your Milestone rank. Each time you visit Atlas you need a specific level, and at the final one you need to be level Magellan or higher.

Once both of these are met you can choose the “birth new star” option. That causes an entirely new galaxy to form and you will be able to start the game over only with all of your knowledge and upgrades.
