Sins of a Solar Empire: Rebellion gets its first expansion pack

Who would've thought you could buy entire new planets for $5? Ah, video games. Today you can do just that with Forbidden Worlds, the first expansion pack to Sins of a Solar Empire's excellent expandalone addition to the franchise, Rebellion.

This time around, that war between loyalists and rebels is still waging—but who has time for drama when there are four new planet types to ruthlessly exploit for resources? There's also a new planet specialization system, giving you the option to expand your planets' social or industrial output. Would you rather a cultured planet, or one that basically exists as a production line for new ships? Additionally, 15 new research subjects and 40 discoverable planet bonuses are added to Rebellion's already-sprawling galaxy.

Forbidden Planets is available through Sins of a Solar Empire's own website , as well as via Steam —because the galaxy can only go without a fresh supply of sin for so long.
