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!

I usually describe this game as the love child of Civ and Starcraft and it is a beautiful child. I have spent more time than I would have liked playing this and its predecesor. A+ game, full of fun and worth every penny.

The game still holds up to this day. There are probably enough reviews for it by now but think: Halo Wars but in space. Its got a small learning curve at first, navigating the space and learning the all the UI elements for a complete newbie is a bit rough and the graphics and engine are getting a bit dated. I bought it this year (2016) and have a good amount of hours clocked for a 4 year old game I never played until now.

Reminiscent of "Star Wars Empire at War's" galactic conquest campaign, but with more depth. Hours of enjoyment, and with the sale going on right now it's more than worth the 10$.

I'm a huge fan of science fiction and this game doesn't fall far from my tastes. The amount of time you can put into this is incredible, there're tons of maps and combinations to playing each race that you'll probably never play them all. And if you ever get tired of winning (or losing, in my case) against a really awesome A.I. you can go online and play with your friends.

Ok so lets start. First off, the time listed played, is one match + the tutorial. I played only one single player map. The smallest one. The time it took me to finish it was over 8 hours. Again this was the first single player map and listed as tiny.

Now I will admit. Part of that was cause I was still getting use to the game. I also kinda limited my self to only upgrading war and defensive upgrades. Leaving out anything that was trade or peace related. This makes it hard cause those upgrades I did not use would help capture some planet types, give better material gathering, give more money, and allow peaceful relations with others in the system so that they did not attack you or even might help ya.

So ya, 8 hours for one tiny map.

This game is fun for anyone who like strategy and long game play. Do not get this game thinking it will be a quick run. There are ways to change the victory setting and not sure how the competitive play fairs. I would imagine there might be some ways to make it go faster.

Also, as far as I can see. There is no storyline or quest line. This is not like Starcraft. You are not doing RTS with a rich story about 3 different races. Your basically playing a glorified chess game. A MASSIVE, BEAUTIFUL, not really that close to chess, chess game.

I was listening to a coworker talk about it and the vids I saw made it look good enough to try. It is, but it is really only good for eating up your time. Need something to just throw countless hours at were there is no story and just plotting and building your forces in hopes you can take out your enemies. Then go for it.

Though if you are not absolutely sure then do what I did and get it at 75% or more off.

I can't say if it's the best 4X style space game, but I've been playing Sins since the original one came out, and am still enjoying the game to this day. Also some very good mods for Rebellion, especially if you like Star Trek.

This is the greatest 4X RTS game of all time. Combine that with one of the best modding communities out there and you have a game that allows you to control the capital ships of pretty much every major sci fi franchise. You want to have iconic battles with Star Wars ships? Go right ahead. Want to get the feel for why humanity was losing the war in space in Halo? Play as the UNSC. Ever wanted to be the Borg and assimilate all those who would dare appose you? Have fun. Or maybe some Battle Star Galatica is more in you alley? The game itself is amazing but with mods it becomes much more. Honestly I would buy this game for 100$ if the decided to price it that high.
