Stardock has announced the first DLC pack for ambitious sci-fi strategy Sins of a Solar Empire: Rebellion.
GameInformer reports the pack is called Forbidden Worlds and will be available for $5 from June 5.
It offers four new planet types to colonize and exploit - Barren, Ferrus, Greenhouse, Oceanic - and a new planet specialisation system allowing you to take advantage of them.
The pack also adds 15 new research subjects, 40 new planet bonuses, and five Steam achievements.
Rebellion is a stand-alone expansion to the core Sins of a Solar Empire experience, and the third Stardock has produced. It launched in June last year.
