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!

My hours do not do my playtime of this game justice, I have over 300+ hours on stardocks launcher before the steam release.

This game is the BEST space strategy game ever released. Perfect mix of RTS, 4X, and even some RPG elements. Every map isnt just a game, its a story of your empire and how you choose to build it. Some matches will be a fast blitzkreig of domination, others will be a drawn out war filled with diplomacy and betrayal. Some matches i emerge victorious and the sole empire, but most I will have been destroyed and defeated by my enemies, watching my planets and fleets fall to the overwhelming enemy. I cant write a review of this game without gushing its every praise, so this is a love poem to Sins and Stardock. Thank you for making this game.

Only 2 negatives in the endless streams of positives
-End game slowdown with large fleets is inevitable, I have a GTX 970NVIDIA, 6600k CPU, 8.97 GHz and I still get slowdown
-No definitive campaign or storymode.

GET THIS GAME NOW, on sale or fullprice its worth it dont worry.

Say goodbye to your free time. Even with all my hours, still have never won a match against a hard AI or an online match.
The 32-bit engine is a little taxing on your computer. I used Large Address Awareness to fix this problem after a while.

this game is like a space version of Sid Meier's Civilisation. the graphics are great, the combat is fun, tense and challenging, not to mention it looks good too, and the micro management is so detailed! you can have entire planets devoted to defence or mining or ship building, or all three at once! the AI is challenging, playing with friends is even better, and there are BRILLIANT mods out there for this game!

i cannot recommend this enough to someone. the only thing i wish was that they brought out more races and ships, because then the fun would go into overdrive!

Totally worth the $12.00 I payed, and totally worth the $43.99 CND it costs normally because you pretty much get 6 games in one as the mods for this game are of such a high quality you could mistake them for straight up $15.00 DLC's, like holy ♥♥♥♥ they are good.

10/10 If you don't like the unit cap or want to change something, just go into galaxy forge or the game constants and do it your self.

Still haven't played the base game though...

What an amazing game to play, it is like if you mixed the fleet command of homeworld and with other hints of star wars style space battles and stargate space battles.

Great value when on sale (as it is often on sale)

Tons of replay-ability with all the mods that are incredibly easy to install. :)

If you dig space combat, complete control of an empire, small learning curve, and great graphics that will run on any system you can buy these days then this is the RTS for me, I have played a few hours.

played a 2v2 match vs hard ai with my friend, this is our story.

-i choose vasari loyalists
-he picks TEC Rebels
-build capital ship
-reccomend ship for friend to start out with
-he ignores me
-immeadiately go on the warpath and conquer 6 planets
-my one capital ship downs enemy capitial ships like a fat man vs a large pizza
-friend mentions that he thinks he can take me due to superior numbers of capital ships
-oh really now?
-laugh it off with him
-finish my titan before him
-focus all effort into researching stripped to the core
-show friend what stripped to the core does
-use resources from stripping enemy ai worlds to build even more capital ships (to the max limit and full basic training)
-notices friend is almost done killing off the other ai player
-secretly breaks pact with friend
-sends my very first and most elite capital ship to engage my friends titan
-ships tanks the titan until half hp
-retreat it to repair at home
-jump in the rest of my aramada
-friend wonders what is going on
-kill friends titan
-friend is most enraged
-attacks my closest world to his armada
-places phase gate with my titan to warp every ship to counter the threat
-easily pick off another two of his capital ships and wreck his frigates and cruisers
-send armada to his homeworld and captures it easily
-strips his homeworld bare
-friend deletes me from his list and blocks me from steam and gets mod to ban me from the ventrillo server

20/10 would turn friends homeworld into useless dead rock again.

This is one of my favorite games. It keeps the micro management from becoming overwhelming no matter how many worlds you have.
Fleet composition can radically alter engagments. Capital ships are key, it feels like the death or escape of an enemy (or your) captial ship can at times be major turning points. Every ship has value, even the first ship you start with can be useful late gam when used correctly. Each world can be a campaign itself with proacted sieges or lightning strikes that bypass enemy fleets and defenses. Capital ships and titans level up through combat to increase their stats and unlock or upgrade powerful abilities. a handful of fully leveled captial ships can be increadibly powerful, they also are an irreplaceable loss if you are not careful. the control within combat is relateivly straight forward but be warrned in larger engagments ships may be unable to act in timely manners. If you tell a damaged ship to retreat it may have to push other ships out of the way, slowing it down. there are other small things like focusing fire to take on enemy captial ships but nothing unsual or complex.

four trees that require you to expand to fully move down (each level requires another research station which take critial slots on your worlds) that each move seperately. It is somewhat boring but there are later powerful and unqiue technologies that can radically alter a game. it is well laid out and easy to understand in a single play through.

This is both simplier and a little more involced than most games of this type I have played when dealing with both AI and human players. The reason being that you cannot overrule the will of your empire. Actions on both sides as well as racial relations can effect how different empires feel about each other. Completeting (and assigning) missions can help but failing missions can have severe concequences. Bribing races with resources can also be used but is limited by the other factors and can serve to push relationships over the edge but will rarely turn foe to friend.

Each race has roughly anologous ship types and some of the most basic research is the same but by the mid game the differences become abundently clear. The TEC, Advent, and Vasari have different strengths and weaknesses that are reflected in their ship specializations, unique abilities and most promanietly on the nature of their captials ships and titans. The Rebellion speciifc split of each faction results in truely have six interconnected races and their natures even effect attempts at diplomacy. The Rebal TEC can align with Pirates and Militas but its hard to gain the trust of other factions and also hard to get your people to accept them in turn.

Culture is a mostly passive system that your choices affects. Both race and research as well as building affect when and how it spreads. Culture allows you to get more resources from remote colonies, it can give you abilities such as visiabiliy of enemy worlds, and it can take planets away or keep them safe. A world overwhelmed with hostile culture will rebel and abandon your empire, conversely an abandoned world covered with your culture will not be colonizable by hostile empires even without your control. its another layer that can drastically change the tide or be nothing depending on how each party uses it.

Hard but streamlined. if you can clear it you can take it and there are only a handful of upgrades each world needs with the option of a few specializations. additionally you can explore to find benefits, powerful artifacts, or debuffs for your worlds. The most important part is always space, what with you use the tactical and logistical slots on each world for can determine if you are rich, smart, capable of producing a fleet in minutes, or culturally dominate.

Overall its one the best games I have ever played. It has been described as 4X lite and I think its somewhat accurate but not a negative at all. Its a streamlined 4X that tries to keep you from being bogged down with minuta while still having a slower more deliberate pace.

Wanna kill a week in a constantly tense and interesting RTS about demolishing your enemies resources?

Start a very large map and alert your neighbors.

This is the best 4X space game. Can play a ton of games, solo or multiplayer, even without a campaign and it will be different and enjoyable every time. (my hours don't reflect a fraction of the time played I had box of original shipped no DRM and playing on digital copy on release of original Sins probably 300+hrs easy not counting mods) The graphics are really good for a game with this scale I did not expect this level. But if your rig can handle it it looks good even with a massive map and ships everywhere. But also huge modding community that is amazing. Once you get tired of it make it Star Trek, Star Wars or Battlestar and enjoy or lose all those hundreds of hours again. Cannot believe they let this title sit idle for so long.

Glad they are releasing new content now and haven't forgotten about the game. Trying to boost publicity possibly? Brings hope for new big expansion or new game! Maybe this time we will get a campaign and finally see who or what the heck that warning was all about!

This is one of the greatest space 4x games ever made. It is RTS so those from single turn will at first cringe, but fear not it is nearly the same. You have full control of your time much like EU. The game is stunningly beautiful. I kid you not you could make a full epic "Star Wars" lilke movie with the actual game play recorded, which is easy to do with in game features.

This has been one of my top RTS games for a long time. I've been playing since initial release, and each expansion adds something fun and worthwhile. It's a little slow as an rts game, which is totally ok since there is a lot to do (some people call it 4x as well). For me this is topped only by Star Ruler 1 and Empire Earth AOC in the strategy genre.

I will say that the game is growing old and has a dying player base, but there is still a plethora of fantastic mods that are still being maintained. Grab a friend or two, or even just fight the AI- it's a great game.
