On Steam, right-click on the game in your library and select 'Properties' then 'Betas.' In the 'Select the beta you would like to opt in' drop-down, choose any past version of the game.

The most recent version of each major patch is available, although intermediate bugfix and hotfix patches are not. In this case, if playing on Steam, a player can roll back to a previous version in order to preserve their current playthrough. Patches, specially major ones, can introduce anomalies or incompatibilities with save files and mods from older versions. Released alongside Synthetic Dawn.īanks: 5th major patch.

When this occurs, a portion of the DLC's features are usually shipped as part of the coinciding free patch, thus made available to anyone who has the base game. They are sometimes released alongside a new, major DLC. Patches fix bugs and/or implement balance tweaks.
