Stardock and Ironclad have announced the release of the Diplomacy expansion for Sins of a Solar Empire, as well as rolling out SoaSE: Trinity which bundles together the base game and both expansions.
The micro-expansion brings a significant amount of new content to the title, including 30+ new technologies to research on the Diplomacy tree, a new relations status screen, the ability to create and issue missions, new maps, and much more.
