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.

- You can now adjust the pitch angle of each gun. - Added some gun skins. - Adjusted the gun unlocks. - Moved the safe house sign higher to prevent accidentally shooting it. - Bug fixes.

For all you nighttime zombie hunters, we found a zombie gnawing on the nighttime simulator cables. He has been disposed of and nighttime should look like the real deal now.
