The beta for Sins of a Solar Empire: Diplomacy pre-order customers is now over. All pre-order customers will gain access to the final version of Diplomacy this coming Tuesday, February 9th. Ironclad and Stardock would like to extend our thanks to all of the testers who participated in the Diplomacy beta and provided feedback. It's no exaggeration that Diplomacy was greatly changed based on your feedback!
For Diplomacy testers: If you update your copies of Sins of a Solar Empire or Entrenchment to v1.19/1.05 respectively, you will no longer be able to play Diplomacy until the final release.
