Ironclad Games and Stardock Entertainment are very pleased to announce the release of version 1.5 BETA for Sins of a Solar Empire: Rebellion. This new update will be available as an opt-in Beta via the Steam client ahead of its final release so that we can get feedback from users on the changes.
NOTE: THE V1.50 UPDATE WILL BREAK SAVE GAMES!
To access the BETA build, do the following:
1) In your Steam Library, select Sins of a Solar Empire: Rebellion, right-click, and select Properties.
2) Click the BETAS tab.
3) Select 'BETA' from the dropdown and click Close.
Steam should update you automatically to the Beta version; if it does not, restart your Steam client to kickstart things.
