The Sins of a Solar Empire world will expand with several expansions during the next year, publisher Stardock announced today.

The first expansion is titled Entrenchment and will be available later this year for $9.95.Entrenchment will add a Starbase defense platform to each race--giving them armored bases with a variety of weapon, and upgrades that make them capable of defending an entire planet--along with turrent upgrades, mine fields and a "Subspace Inhibitor platform" which will slow down nearby enemy ships.

Other micro-expansions in development will add new diplomacy features, as well as additional technologies and ships. Development of all these expansions is being handled by series creator Ironclad Games.

The expansions will be available from the Sins of a Solar Empire website as well as through Stardock's Impulse digital distribution platform.
