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 best memory, played this game with my friends for 8+ hours each time. Every stage of this game is fantastic, early exploring stage, middle developing stage, late battle stage. You need to be patient and better play this during weekends without plans XD

This is the best game I know. Fantastic 4x play that kept me coming back for years, and I think it will be a future classic. There are about a half dozen full environment mods for this game and lots more resources in general. We need a strong, 64 bit reboot of this game that allows us to use the power of modern computers. I know I'd buy it and every DLC they come out with.

So what's good about this game? Well let Swerve tell you! This is going to be long as hell since I used to play the orginal a crap ton 3 years ago! So gather round children! Grab a seat and listen to the great story I am about to tell!


The game provides a pretty solid diplomacy system that fits in very well with the backstory of the game. This means that it's harder to ally with Vasari rebels when you're a Vasari loyalist, unless you already premade the teams ofc. The computer or player can give you missions, if you choose to do them will improve your relations with them. Eventually if they like you enough they ask for peace treaties, powerful pacts (These buff both of your factions), trade agreements, ect. Even though diplomacy is useful in a game, it's not the core aspect of this game, you shouldn't buy it expecting it to be a game like Anno 1404 where war is only an option.
Your goal is to kill everyone, not to make peace with them.

Overall it's a nice mechanic, it fits with the story, highly dynamic, and very diverse, but not the main focus of the game.


Personally, I think the combat is very simple.
You have your ship types:

-The Frigate : Light, fast ships. Most are used for offensive means such as taking out strikecraft or bombing planets. Some are better at taking out other ships than others. I wouldn't call it rock paper siscors but it's kinda close to it.

-The Cruiser : More expensive, but provide much more firepower and/or support than frigates. Enforcers/Crusaders/Kodiacs are probably going to be the front line of your fleet.

-Srikecraft : I feel I had to put this in somewhere. Strikecraft can only be created by Carrier Cruisers or Capitalships/Titians. They cannot be targeted by normal ships so you either need to counter them by using more strikecraft or use specialized frigates to take them out. They do a crap ton of damage if you leave them unchecked.

Strikecraft have 2 types:
-Bomber (Good at taking out bigger ships)
-Fighters (Good at killing bombers)
-*Advent only* homing mines (They're mines)

-Capital ships: These are essential for any fleet. They are very expensive *You get your first one free, so pick wisely" and very powerful ships that provide ALOT of utility and/or damage to the fleet. They are tanky, and usually the first, or last to go down. They act like Warcraft 3 heroes where they level up if you gain enough experience from killing things. These levels unlock abilites for your capital ships that do various things. (Ex. Kol Battleship, The ability "Finest Hour" gives him massive Health Regen and lowers cooldowns on his other ablities)

-Titians : These things a freaking scary. Huge warships each faction/subfaction gets a specific one. They do alot of damage, they provide HUGE utility (Ex. The TEC Loyalist Titian buffs his allys with reduced weapon cooldown and gives them all more shields). It takes 5 points of research to fully build one, and even then It costs alot of money. It's best used in late game.

-Starbases : These things are broken. I've turned around entire games using these things. They do LOADS of damage. You can counter them with a ship specialized in destroying buildings, because they out range them, unless you put them in the middle of the damn phase lane! Thats right, you can place them right where you enemy will enter and they wont even get a chance to say their prayers. And if you're TEC Loyaist, you can have 2. gg

If you ever play TEC Rebels you need buy a pirate fleet. Seriously. They have the best voice acting N/A. It's hilarious. There will be a pirate base on almost every map, you can place bounty on annother faction and they will attack the person with the most bounty. They don't have shields, they're kinda easy. Cool feature tho.


I think the ships are very well-designed. Each have their own jobs and none do the exact same job. They all look very different from one annother and are very detailed. They're voice acting is very professional. Overall they did a good job in diversification the different ships.


The victor of a battle is mainly determined by whoever has the best ship composition and the most research. It's very rock paper siscors-esk. It's simple, you have shields, that protect the ship for so long and then breaks and then it does health damage, if it reaches zero the ship splodes.
There's no complex locational damage, They all just kinda stand still and hit eachother until they die. Realistically, no captian in his right mind would just stand there and let his ship get rekt. But it's based off an old engine so I'll let it go.

However! The battles are epic as hell! Pretty lasers, Strikecraft flying all over the place, Capital Ships using they're cool
guns. They look very pretty, but nothing else.


Economy is simple as well. The 3 resources you have is Credits, Metal, And Crystals. You can get credits from planets, which you can upgrade to house more people to tax. You can get metal/crystal from extractors that can be built on asteriods orbiting the planets. You can also research and build trade ports and oribal refineries/Matter Processers. TEC are very good at amassing credits. The Vasari are very good at getting minerals. The Advent are mixed.

You also have a thing called "The Black Market" where you can buy and sell metal and crystals. It acts like a regular economy and if you sell too much the market crashes and it sells for literally nothing. If you buy too much the market booms and I think the price goes up by alot. Doesn't stop me from buying crystal tho, because lord knows I always need crystal. >.>

Every resource is renewable. It will never run out. However the more fleet upgrades you invest in, the more it will effect your economy (7 to 80% deduction without pacts/supply reductions). It actually makes turtling viable, and I KNOW EVERYONE ABSOLUTELY LOVES PEOPLE WHO USE THE GOOD OL' TURTLE STRATEGY.

Overall the economy is like every other RTS. Just without gatherers or giving a damn about exhausting resources.

The Art:

This game is beautiful. I love it. Every planet, ship, and building is 1080p and professionally crafted. The battles are awesome because of all the colorful lasers. Every race has different ships which look just as professional as all the others.

Voice Acting:

Good stuff mayne. Professional voice acting. The voices fit the theme in ships ( Ex. TEC Rebel Titian "I put the laughter in slaughter!"). Everything just fits.

P.S. Whoever voiced the pirate ships deserves a metal.


Even though this game has no campaign the opening cinimatic really gives you a good feel of the current state of the universe. The whole ambiance of the game gives off a desperate feel. Every race is tired of fighting, but cannot forgive eachother for the horrible atrocities that they committed against eachother (Hence the name Sins of a Solar Empire). Every side will do whatever it takes to win.

If you want to buy this game for story, there really is none besides the opening, sorry, play Mass Effect or something.

This game brings a unique twist to the 4x genre. Providing a slow pased game that keeps you interested and on your toes. It includes a large research tree, many ships to choose from, very diverse races, and very pretty art. Though kinda simple it still holds a place in my heart. This has to be one of the best 4X games I've ever played.

I'd say it's worth buying.

(insert X/10 joke here)

My favorite RTS of all time, if you miss having an RTS that isn't based on hyper speed clicks or over in 5 minutes (starcraft 2 , C&C, warcraft 3, etc.) or based on super hero units with just a couple side units then this is your game.

This is by far my favorite strategy game.

For those of you who are new to Sins it will be a bit of a challenge figuring out how to play the game but trust me put the time in and it pays off. The difficulty of the game can be tweaked to suit anybody's needs, wether your'e looking for a quick 1 on 1 match against an easy opponent or an 8 player free for all against ruthless AI, or compete against real human beings online. Be warned though, matches can last for hours and hours, this can be a good or bad point depending on your play style. Visuals are great, so much satisfaction to be had in zooming all the way in on your massive fleets and watching them demolish your rivals empire in flurries of lasers, and explosions.

Long story short, if your'e into games like Total War, Glactic Civilizations, Supreme Commander then your'e definately going to want to pick this up. 40$ is a little steep though so look for it to go on sale, I was able to pick it up for 8$.

Sins of a Solar Empire Rebellion is one of the best Strategy Games i know and maybe the best Galactic Strategy Game. Lets begin with the Gameplay. You can choose between 3 Races: TEC (Trader Emergency Coalition) they are human, The Advent was originally a desert religious cult that mastered psychic powers and The Vasari they are the only alien race in the game. A new feature: For every race (TEC,Advent,Vasari) you can choose between Loyalists and Rebels both of them have their own advantages and abilities. You have many possibilities to start a game (defensive, offensive or aggressive) but to win at the end you have to attack the other empire (other players or KI). The intelligence of the KI is pretty well and if you play on a higher difficulty like unfair its really hard to win the game especially if you play agains more than one player for example 5 or even more. (10 players max.) The graphics are really nice and the galaxy with all its stars solar systems and planets looks just awsome. Only if you zoom really close to the planets you will see that their surface is fashioned a little bit boring. But all ships, frigats, star bases and structures look nice and really realistic. One of the coolest features in this game are the Titans the biggest ships you can build. Every player can only have one Titan at the same time because theyre really strong especially as support if you attack with more capital ships and a fleet. Only a full developed star base can fight against this strong ship. You can play in small solar systems with 9 planets or you can choose the biggest map: a galaxy with five solar systems and about 150 planets. Thats really big and you will need a long time to discover the whole galaxy with all its secrets and resources. Resources a one of the most important things in the game you can earn: credits (from: taxes, war and allies) metal (mainly from extractors but also from allies and war) crystal (mainly from extractors but also from allies and war). As soon as you have enough recources, planets and a few defensive structures you can start to discover the galaxy and to build your fleet with many little ships, capital ships and you big Titan. Then you can attack other empires to get their planets because for a big empire you need much space. But maybe the will attack you before you you are ready and thats the difficulty with this game: YOU NEVER KNOW WHAT HAPPENS NEXT! Thats what makes this game so interesting. Lets come to an end: This game is worth buying! You need to invest time but once you have understood everything the fun begins and you can start building many empires.
I hope i could help you. :)

I've had this game for so long now. Every now and again I even google to see if they will ever make a 2nd one. The gameplay is so deep and fun. You really feel like this could be the future! You can zoom out and see the galaxies at your disposal and zoom back in the see the fighters fending off the enemy. I get so much enjoyment out of the game, HOWEVER!

I have played this game on multiple computers, all very high end gaming machines. Quad Cores, i7s... Radeon 7990's ect. These machines are made to game... But this game is not made to game. You can do so much but at the same time you are limited by old software. I have never been able to play a full game with more then 80 planets (which in this game is not a lot)

I find myslef always having to play short small games, anything large you will start lagging maybe only an hour into the game. There is so much potential here and it is still fun but I think the game has past its time and the developers really need to create a new one from scratch that is capable of taking advantage of my machines and giving me a incredible gameplay experiance.

Just want to say this game is one of the best that I have ever played! Its design and gameplay is just perfect. The level of detail on a game of this scale is brilliant! One thing I will mention is the lack of Steam Workshop support, but with a bit of patience and a quick look on the web, you can find loads of tutorials on installing the many mods that are available.
I personally play Sins with a total conversion mod called Star Trek: Armada 3. Anyone who is a Trek fan, I highly recommend that you give it a try. Heres the link to the webpage:
Also there is a Star Wars mod. Thanks for reading and I hope you love the game like I do!!
