Sins of a Solar Empire (Sins or SoaSE) is a real-time strategy (RTS) game that incorporates a mixture of RTS and 4X gameplay, this has been jokingly called RT4X. The game was developed by Ironclad Games and published by Stardock Corporate in 2008.


Sins of a Solar Empire takes place in multiple star systems across the galaxy. While there is no campaign, the premise of the game is introduced via an introductory cinematic. An ancient alien race (known as the Vasari), which is on the run from some mysterious threat that has been chasing them for thousands of years, arrives in human space and begins a conflict with the human race (organized under the banner of the Trade Order). The Human race was losing on all fronts until the TEC was formed to combat the alien threat.

The humans seem to be making ground against the Vasari onslaught for some time, but in the midst of this progress, the past arrive to haunt them. One thousand years earlier, the trade order banished a group of "deviants" from a small desert world orbiting a red star for committing "acts of deviancy, at every level of society". They have returned as the Advent, a powerful, advanced, psychic army which is determined to seek revenge against humanity for their banishment.

The three races are now locked in a seemingly never ending war with each other.
