Branches

Depots

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Every appinfo change SteamRaw has observed, grouped by changelist. Tags, features, languages, builds, depots, prices and any other key Steam publishes. Tracking since 12 September 2026 08:20 UTC.

No changes recorded since SteamRaw first saw this app. Every future PICS change will be listed here.
