Stardock today announced that Sins of a Solar Empire, the popular real-time space strategy game developed by Ironclad Games, will feature several micro-expansions over the next year. The first expansion pack, Sins of a Solar Empire: Entrenchment is currently in development and will be released late 2008 for $9.95 via Stardock's Impulse digital distribution platform. Sins of a Solar Empire: Entrenchment will feature 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.
