Sins of a Solar Empire: Rebellion v1.91 Released

9/27/2017 11:17:11 AM

Ironclad Games and Stardock have released a small update for Sins of a Solar Empire: Rebellion today. The new v1.91 build fixes two issues:

  • Fixes the user interface scaling for missions
  • Fixes 'Failed to Initialize COM' error

Both mods and save games should be unaffected by this update.

v1.9 Update marks 5 Year Anniversary for Sins of a Solar Empire: Rebellion!

4/4/2017 1:00:00 PM

v1.9 Modernization Update Improves
Sins of a Solar Empire: Rebellion for Current PCs

Get Sins of a Solar Empire: Rebellion on Steam for only $10!*

Sins: Rebellion celebrates its 5-year anniversary with an update that brings significant changes to the game's engine, AI, graphics systems, and more! Modern gamers will enjoy an incredible remastered 4K experience, optimizations to late-game play, and improved memory capabilities.

Major Features

Graphics Optimizations
Sins: Rebellion gets a face lift in v1.9! The improvements to the memory system have allowed for a new "Extreme" texture setting that makes the game look better than ever. The difference is noticeable in everything from the ships and the planets all the way to shadow rendering. The UI will look incredible on 4K monitors now thanks to user interface scaling.

Memory Optimizations
Concern yourself with space battles instead of space restrictions! Previously, Sins: Rebellion's 32-bit process was unable to exceed 2 GB of RAM usage. New adjustments in v1.9 allows the game to use up to 4 GB of RAM, which reduces crashes and lets modders focus on their creations instead of worrying about hitting the 32-bit limit. Any mods that already exist will benefit from the engine improvements with an overall better look and performance.

Late Game Optimizations
Reduced stuttering and lag during late game battles let you focus on the fight! The Iron Engine has been improved so you can enjoy large fights without worrying about issues. The game's AI has also received some updates, making for more interesting challenges and gameplay.

For a full changelog of version 1.9, see here.

v1.9 is available and ready for you in the Steam Client!

Sins of a Solar Empire: Rebellion v1.86 Released

11/15/2016 12:58:16 PM

Ironclad Games and Stardock Entertainment are pleased to announce the release of version 1.86 of Sins of a Solar Empire: Rebellion today. Today's update further optimizes the CPU and AI systems, while including several fixes for the Outlaw Sectors DLC. 

Change Log
  • Advent Reanimation and any other form of cloning will no longer clone Militia units. 
  • Truce Amongst Rogues is now with just the pirates - not rebels, neutrals or militia. 
  • Modders can now make use of the new ResearchModifierTypes "FriendlyWithPirates" and "FriendlyWithRebelNeutrals" in addition to the original "FriendlyWithPiratesRebelNeutrals".
  • Fixed smuggling data showing up when looking at crystal or metal tooltips. Smuggling only affects credits. 
  • NPC and Militia carriers now build their strikecraft squadrons. 
  • Militia will now spawn carriers. 
  • Militia no longer receive research benefits that are tied to weaponclass. This solves the problem of races who don't use the militia ship classes being at a research disadvantage. 
  • Mod users no longer need to move their mods to a new mod folder if the executable version changed unless the new game version breaks the previous version's mods. (e.g. 1.85 mods can stay in the Mods-Rebellion v1.85 folder even though this is game version 1.86). 
  • CPU optimizations in large battle situations, late game situations and mass militia situations.
  • Reduced memory usage (particularly during large battles). 
  • Reduced memory fragmentation (particularly during large battles). 
  • AI CPU and memory optimizations.

Outlaw Sectors brings new maps and gameplay to Sins of a Solar Empire: Rebellion

6/22/2016 1:00:00 PM

Outlaw Sectors DLC is here with new gameplay and lots of new maps 

Challenge yourself with new strategies and unique setups with the new “Outlaw Sectors” gameplay option and brand new maps for Sins of a Solar Empire: Rebellion. The variety of map sizes and designs will let you enjoy any kind of match you want, from intimate 1v1 duels all the way to epic 10-player brawls.

Outlaw Sectors Gameplay
The lawless fringe is increasingly hostile, but for those with a criminal mind it's also rich with new opportunities.
  • Smuggling Specialization: Choose this planetary development to grab a cut of everyone's trade
    income - but at a cost. The increased corruption from this black market activity will reduce that planet's tax income.
  • Rampant Militias: Autonomous planetary militias will grow, raid nearby systems, and repopulate over time. Use them to help defend your worlds, or coordinate your attacks with their strikes for maximum impact.
  • Pirate Turf: Vicious when in their home sector, pirates can now raid multiple players simultaneously, drastically changing the art of the bidding war. And, just to make sure they are fully motivated to do what they do best, all credits spent on bounties will receive an automatic bonus.

Included Maps
  • Power Struggle - Contest the distant resource fields and nearby planets before striking at the enemy’s homeworld.
  • Slim Pickings - Claim what remains among the war-torn stars and seize what you can from the other empires.

  • Crossfire - Take your enemy’s homeworlds and coordinate your assault with your ally in order to win.

  • High Stakes - Build a powerful fleet and seize the resource rich planets from enemy militia.

  • Ironheart - Flanked by an enemy on each side, you must prioritize your resources carefully to achieve victory.

  • Titans of Cimtar - Secure your planet from among the 8 gas giants dominating the map, then make war upon your neighbors.


  • Death Spiral - The system is falling into a black hole and your enemies aren’t about to let you leave without a fight.
  • Dogfight - Lead your allies into glorious battle amongst the stars in this huge map.

  • Buzzsaw - Make one mistake and you may lose more than you bargained for in this spiral galaxy that leaves no room for error.

  • Rising Empires - Secure your star system amidst the crushed local resistance and set your sights on your rivals’ territories.

  • Desolation - Claim what little the Vasari have left behind and forge what remains of the worlds in the massive cluster of stars into a force capable of conquest.

Outlaw Sectors DLC is now available on Steam or through Stardock
