Update 3 now on Public Test Branch
Update 3: Custom Game is now available in a pre-release build on the Public Test Branch (PTB for short) on Steam.
The PTB contains a work-in-progress build that may contain some game-breaking bugs and errors. But it will let you jump in RIGHT NOW to the playtest and enjoy the newest unreleased content, features and mechanics on which you can share your feedback with us.
How to Join the PTB (Public Test Branch)
Accessing the PTB is straightforward:
- Open Steam and navigate to your Steam Library.
- Right-Click StarRupture and select "Properties" from the context menu.
- Select "Game Versions & Betas" Tab.
- Select “Public Test Branch”.
- Steam will automatically download the necessary update.
To switch back to the official live version of the game, simply click "Default Public Version" from the list of Game Versions & Betas.
Save Compatibility Information
As the game evolves over time in Early Access, we’re changing and improving the underlying game code to some crucial game mechanics and features. With Update 3, we’re adding a little pop-up information which informs that the save file you’re trying to load was made on an outdated version of the game (before Update 2). You still will be able to load these legacy save files, but they may not work correctly. For the best experience we recommend creating a new game session.
PTB Game Continuity
When entering PTB you will be able to continue your progress from the main game, but please be aware that the save made on the Public Test Branch won’t be compatible with the build on the Public Default Version branch, once the Update launches.
Backing up your saves
As we are doing our best not to tamper with your game save files, we cannot stress this enough - please, please back up your saves before switching to a PTB version of the game. To do so:
- Open Steam and go to Steam Settings > Storage.
- Next to the size of the installed files bar, click the three dots (•••) > Browse.
- This will open the 'steamapps' folder in Windows File Explorer.
- From there, click on 'Steam' in the address bar and look for a folder called userdata.
- Inside userdata, you will see folders named after your Steam ID(s). If you have multiple Steam IDs, you can sort the folders by the most recently modified to find the one you've been using.
- Once inside your Steam ID folder, look for a folder named 1631270 > remote > Saved > SaveGames.
- Copy the entire folder and place it in a safe location: for example, your Desktop.
Sometimes, Steam may not recognize this path correctly. If the files do not appear in your remote folder, please try the following path: C:/Users/ /AppData/Local/StarRupture/Saved/SaveGames
Additional important considerations
- There is no Dedicated Server available for the Public Test Branch, as we’ve ended active support for dedicated servers. You can read more about this announcement in October's Developer Blog.
- Content in the Public Test Branch is still under active development and may contain bugs, incomplete features, or placeholder assets.
- The Public Test Branch will receive updates of unknown frequency.
- While we strive for the best stability of the game, the PTB may be less stable than the live version of StarRupture.
