Ironclad Games and Stardock Entertainment are happy to announce the release of the v1.51 update for Sins of a Solar Empire: Rebellion and the Forbidden Worlds DLC today. Now available automatically via the Steam client, this new update fixes several reported bugs by users.



  • Fixed Occupation planet mesh and texture to display as intended.


  • All Envoy cruisers are now really 4 Fleet Supply (from 8).
  • All Envoy cruisers are now worth 4 XP when destroyed (from 8).
  • Fixed bug that would cause non-DLC owners to generate fewer planet bonuses than DLC owners.
  • Advent Rebels - Wail of the Sacrificed damage now correctly scales at level 2.
  • Forbidden Worlds DLC - Added missing strings to in-game map creator for new planet types.
  • Forbidden Worlds DLC - Fixed bug with Population not updating / reporting properly once a planet is specialized.
  • Forbidden Worlds DLC - Added Allegiance to InfoCard system for planet bonuses which modify it.
  • Forbidden Worlds DLC - 'Forbidden Worlds DLC' will now be displayed under the version string if owned.
  • Forbidden Worlds DLC - Fixed bug related to galaxy generation and Ferrous planets not spawning.


  • Fixed in-game map creator so that the Forbidden Worlds DLC planet types are not selectable if the DLC isn't owned (was causing the game to hang).
  • Non-random maps will now properly select available planet types based on DLC ownership (varies per map and if the map called for a random planet type).
  • Forbidden Worlds DLC - Fixed broken string on Ferrous planet achievement (Drill Baby Drill).
  • Fixed bug that would cause the game to hang if someone tried to load a map or save game that used DLC when they didn't own the DLC pack.
  • Reverted back to the ICO server as some users were not able to reach the new one.
