About the game
In this Sins of a Solar Empire: Rebellion add-on, the fighting between loyalist and rebel forces from the TEC, Advent, and Vasari spreads into the heart of Trader Space. That corner of the galaxy hides more territory and backstory than any faction realizes, and the need to survive pushes them all outward into uncharted territory, where dangerous, valuable, and mysterious worlds wait to be found. It was developed by Ironclad Games Corporation and Stardock Entertainment, and published by Stardock Entertainment in 2013.
