sentinel

The Sentinels are Mechanical Lifeforms; self-replicating, non-organic machines that are similar to the Korvax, another Mechanical Lifeform in No Man's Sky's Universe. Their origins are unknown but they are seemingly deployed on every known planet to balance the efforts and actions of the player within the procedurally generated ecosystem. Sentinels act as the workhorse machines of The Atlas and as universal police, policing the actions of those who reside within the universe. They are, in essence, the "gardeners" of the No Man's Sky universe. If the player makes an attempt to alter the environment while they are around, they will not hesitate to defend their "garden." They will attack the player if caught harming the ecosystem of a planet. A Sentinel will also defend itself if the player shoots it, alerting other Sentinels in the area. On planets with rare tradeables like Gravitino Balls, the Sentinels will attack the Player instantly after scanning them once.
