No Man's Sky is an upcoming adventure survival video game developed and published by the indie British studio Hello Games. Players are free to explore the entirety of a procedurally generated deterministic open universe, which includes over 18 quintillion (1.8×1019) planets, many with their own set of flora and fauna. By exploring, players will gain information about the planets that they can submit to The Atlas, a universal database that can be shared with other players of the game. Players also gain materials and blueprints to upgrade their character's equipment and purchase a variety of starships, allowing them to travel deeper into the center of the galaxy, or trade with other ships. Some activities will draw the attention of Sentinels which will attempt to kill the player-character for killing too many lifeforms or draining too many resources from these planets. Players participate in a shared universe, with the ability to exchange planet coordinates with friends, though the game will also be fully playable offline; this is enabled by the procedural generation system that assures players will find the same planet with the same features, lifeforms, and other aspects once given the planet coordinates, requiring no further data to be stored or retrieved from game servers.
