The file refers to a specific build of the underwater survival game Subnautica that was released on February 17, 2023 . While this date is nearly five years after the game's full release in 2018, it marks a significant period in the game's late-stage development history, primarily involving technical updates and compatibility fixes. The February 2023 Updates

: While official branches were removed for safety, some users continue to use tools like DepotDownloader or the Steam console to manually retrieve these specific older manifests for mod compatibility. Safety and Legitimacy Warning

: The removal was a response to a security flaw found in Unity engine versions used since 2017.

In late 2025, Unknown Worlds removed several older versions of Subnautica , including the early 2023 versions, from public Steam branches.

During February 2023, several builds (such as Build 10576834 and 10576699) were uploaded to Steam, though many were not accompanied by official public patch notes.
