Through the game's procedural generation system, planets have their own ecosystems with unique forms of flora and fauna, and various alien species may engage the player in combat or trade within planetary systems.

Players are free to perform within the entirety of a procedurally generated deterministic open world universe, which includes over 18 quintillion planets. The game is built around five pillars: exploration, survival, combat, trading and base building. While Hello Games and Apple have claimed that ports for macOS and iPadOS were in development and planned for release in 2022, the port was never actually released, and neither Hello Games nor Apple have provided a status update. It was released worldwide for the PlayStation 4 and Windows in August 2016, for Xbox One in July 2018, for the PlayStation 5 and Xbox Series X and Series S consoles in November 2020, and for Nintendo Switch in October 2022. No Man's Sky is an action-adventure survival game developed and published by Hello Games.
