The first expansion pack for Sins of a Solar Empire, Entrenchment, will be released for $9.95 later this year.
Two more expansions are planned adding diplomacy plus technologies and crafts.
Entrenchment add-on contains “a Starbase defense platform for each race (extremely powerful and armored bases housing a variety of weapons and other upgrades capable of defending an entire planet), turret upgrades for each race to make them more powerful (not only stronger than the current versions, but also upgradable with long-range weapons), mine fields and a Subspace Inhibitor platform that will slow enemy ships within its range.” Brad Wardell Satrdock CEO explained.
