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

Outlaw Sectors DLC is here with a new gameplay option 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.

Gameplay Options

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.

About This Game

The Next Installment to the Award-Winning RTS.
While many were hopeful that diplomacy would finally end the war, differing opinions on what should be done, along with the depleted power of the controlling factions, has led to a splintering of the groups involved.

The loyalist members of the Trader Emergency Coalition adopt a policy of isolation, focusing on enhanced defenses to ride out the rest of the war. Those who rebel against the coalition take on a purely militant view, coming to the opinion that the only way to bring peace is by ultimately crushing all who oppose them - especially xenos.

For the first time in their history, the war creates a schism in the Advent Unity. The loyalists seek to continue their policy of revenge against the Traders, and to assimilate all others to the Unity’s influence. However, others amongst the Advent suspect that a corrupting influence from within has diverted the Unity from its proper destiny.

The divide created in the Vasari Empire is less pronounced, but just as severe to their people. With the Vasari now practically frantic to move on to new space, the loyalist faction abandons cooperation and decides to take the resources they need by any means necessary. Having accepted the need to work together, the rebel faction feels that their best chance for survival is to work with the other races and bring them along to flee the approaching enemy.

Take the battle for galactic supremacy to its ultimate level in Sins of a Solar Empire: Rebellion – a standalone RT4X game that combines the tactics of real-time strategy with the depth of the 4X genre (eXplore, eXpand, eXploit, eXterminate).

Key features:

  • New Factions: Decide whether to play as a Loyalist or Rebel – each unlocks new technologies, ships and play styles for each race.
  • New Titan Class Warships: Mighty titans enter the fray of the war to tip the scales of power. Each faction may field their own unique titan, drawing upon unique strengths and abilities on the battlefield.
  • New and Updated Capital Ships: A new capital ship joins the fleet for each race to offer even more tactical options. Additionally, all existing capital ships have been upgraded to four levels for their abilities, allowing players to focus their ships along specific strengths.
  • New Corvette Class Ships: Small and maneuverable, each faction has developed a new light attack craft to harass enemy forces.
  • Updated Visuals: Updated graphics, particle effects, lighting and shadows, race specific UI and other enhancements make the Sins’ universe look better than ever.
  • New Victory Conditions: Take multiple paths to victory including – Military, Diplomatic, Research, Last Flagship Standing, Last Capital Standing and Occupation.
  • New Audio: More than 60 minutes of original music, countless new sound effects and dozens of new voice overs help bring the drama of battle to new levels of immersion.
  • Tutorials: New and updated tutorials make it easy for both experienced and new players to quickly start building their own solar empire.
  • Plus, a number of optimizations that provide better performance than ever before!

Fantastic game, Tons of variables, fleets, different types of worlds to conquer. You need alot of RAM. Love to run this game, but late game with all the AI's and Ind. objects the comp. will easily use 12 gigs of ram and 4 gigs of VRAM if you want to run on max settings at 4x speed (1x is just too slow and even 2x early game can be too slow.)

Sins of a solar Empire Rebellion. This game is probably one of the best games ive ever touched (digitally). hile being a more simplistic 4X game, the style in which the RTS elements are incorporated make up for that. SoSER keeps you on your toes when playing and with some maps makes you work for victory. You can spend hours upon hours playing a single game as some of the maps are huge ranging from 1-10 star systems. Along with all the positive things myslef and others have mentioned, the mods for Sins is astronomical. There are so many to choose from which gives it a ton of replayablability on top of what it has already.

This game is so ♥♥♥♥ing cool. I wish I had picked it up earlier.

Massive ships in space shooting things and blowing up.

It's a good game too I guess. It's good to note though that if you're going to sit down and play through a game... Set aside several hours, this game has a very slow pace since it's on an interstellar scale and all.

This game HAS NO SINGLE PLAYER CAMPAIGN. All you can do on your own is play skirmish against computer opponents that are programmed to simply spam superweapons at you.


This game studio refuses to fix GLARING ISSUES yet keeps making worthless little DLC to bleed customers. Another company engaging in scam behavior for the modern scam economy. Ignore the fanboys who treat multiplayer players like garbage and DO NOT BUY.

To start im gonig to have to lay in this disclaimer, I easily have over 2000 hours in this game so you cant go by the 120 hours steam thinks I've played. So when I saw that this was on sale this weekend being an old player since the original game I just had to leave my opinions. Which arent relevant because this is simply just the best and most amazing space RTS that has since been released since sliced bread. If your going to get this game and play dont sell yourself short, just get the whole DLC package with it. It is easily worth every penny even if you have to sell your children to afford it. I'm not even going to get into the uh-MAZING StarWars:Interregnum or StarTrek: Armada 3 mods there are. Well maybe a little. StarWars: Interegnum adds the Rebels and the Empire into the game along side the original 3 factions with INCREDIBLE balance while ST:A3 is a total conversion... (you guessed it) startrek mod. Interegnum easily takes the cake being the best mod available since it supplements the vanilla in ways I've never seen mods for other games ever do, plus there are about a dozen great minimods for it.

This game is frequently on sale for $10.00 every few weeks.

It's by far one of the most unique rts/management games I've played. I owned it on disk before I found it on Steam.

The game is much more of a management based game than it is an RTS. You move around large fleets of ships from planet to planet. The game allows you to let the ships automatically battle with enemy fleets, which is a good thing because once your fleets reach a specific size you will never be able to micro manage them.

From screenshots and gameplay this game looks very deep and hard, but it really isn't. It's fun once you put a little bit of time in it. It has a great single player experience where you play against the AI. There is no campaign or anything, but that doesn't take away from the single player value.

Overall, a great little game. But wait for it to go on sale. There's really no reason to spend full price on this game.

Sins of a Solar Empire has consumed many hours of my time, all of it worth it. Before I started playing some of the many mods available, the vanilla version was very simple to get involved in and the learning curve wasn't to harsh. I eventually found Sins to be addicting and devoted many hours to playing.

I eventually moved onto mods. Specifically: Sins of a Galactic Empire; one of several Star Wars mods available, but the one I found suited to my kind of "fun."

Some Features:

- Large Matches, up to 8 players, either with friends, other players, or AI (with varying types of AI difficulty sets)

- Different victory conditions for those who like to switch it up or like to change up how to win their game

- 3 vanilla factions to choose from, 2 sub-culture for each faction for different types of playthroughs

- Active mod community with varying amounts of mods that range from Halo to Star Wars to Star Trek

While this may be a dated game, a new DLC was recently released which was a nice surprise to find. So if you ever tire yourself of vanilla, you can certainly utilize the new DLC

You will lose some games and you will spend hours upon hours in some, it all depends on the challenge you set yourself up for.

I would recommend this game to any of my friends and certainly have already and play often when I have time. It's a great game with little flaws, but overall, it's a great game and it does what all games should do: provide fun.

Sins is truly one of the best strategy games ever made. Played 100's of hours before I even bought it on steam; thats right this game is so fun that I have bought it twice. If you are looking for a epic 4x game, look no further.
