I picked up the game again last month and stumbled upon some info about the ARG. Finally found out about this site. I know I’m really late to the scene, is it still possible to get involved/play? And where is the best place to read and catch up.
Thank you!
The ARG is currently inactive and we don’t know if it will start up again or not.
Yes, the ARG is over but NMS continues to be updated and refined. Feel free to explore the No Man’s Sky topics and enjoy the many wonderful pics and stories. Welcome to the nicest NMS community in the Universe.
