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!

A great space RTS. The DLC makes the game much more enjoyable as well with Starbases, Titans, and more kinds of planets to colonize. I've spent many hours late/early playing with my friends. Also, just when I thought I was getting bored, I figured out the Galaxy Forge (included) which enables you to make fully customizable maps, much more detailed than the in game map designer. One drawback to me is the lack of a single player campaign, but as a sci-fi and RTS fan, this game has the most hours out of any in my library.

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.

It's worth buying this just for the Star Trek Armada 3 mod. Even without the mod, Rebellion is excellent. Great depth and compelling gameplay. You owe to yourself to play it.

If you enjoy space battles and strategy, there is no reason you shouldn't be playing this game already. The vanilla game is good enough, but the real fun comes from all the awesome mods that the community has come up with. Star Wars, Star Trek, and Halo all have fantastically well made mods and the replayablitiy is nearly endless.

Pseudo-complexity, the bad AI and a graphic engine made for 19'' Monitors makes this game unworthy for me today.
Sadly I couldn't give it back after reading the tutorial text boxes which took me more than two hours.
Missing story and grid controls in an RTS rounded out my picture of the game.

Combines the original and previous expansions into one solid game. Allows for various mods for even greater replay value. 10/10 would always conquer the galaxy multiple times as different factions from different space fandoms.

Get this game if real time strategy and space empires satisfies your lust of galatic domination.

Colonizing new planets = 2 hours. Fighting pirate raids = 4 hours. Making allies = 5 hours. Expanding your empire = 8 hours. That moment you realize you've won = timeless.

This game woke the Darth Vader inside me...
"Attention! A hostile experimental weapon is being constructed in a distant planet!"
*me looks where it is*
*press 1* *Novalith Cannon selected*
*unleashes the total fallout on the planet that was building that experimental weapon*
*goes back to spamming the market button like nothing happened*

P.S: Still on the first game I played on this game...

Good overall game, but suffers from major engine slowdowns as the game progresses into having hundreds, and then thousands, of active units, which on the large to huge maps you will definitely have.

This game... Oh, this game. Where to start?
I will start with this:
If you like RTS games, then this is the one for you. I have had this game, and the prior one, for years as I had purchased them from Stardock. It is a futuristic, space themed strategy game that expands many solar systems and you can colonise everythings, except for the stars, as long as you have the proper research.
The longer you play, the easier it gets, but at the same time, it also gets harder and the dificulty setting increases (as usual). But the jump in dificulty is amazing as you try to play on the highest setting.
There are people online that will ever tear you up at every chance the get, so get your economy going and making your fleet of ships something to be feared.

It's not perfect, but as someone who has played a lot of both RTS and 4X games this is about as perfect as it gets at the moment (okay, okay, I've not played every game out there. I'm happy for folks to buy me games and I'll compare and contrast, though ;) ).

There's a bit of learning, and I'm not finished there yet, but I do feel I have options in what playstyle I follow. I have played mostly with some friends, and we've tried both vs and co-op (plus, recently a mix). Human oposition is better, of course, but my only real with is I could design some maps with a bit more detail - there's three of us at times, and I'd love to create a 2 vs 1 game (with resources to suit) rather than have a tenative 1 vs 1 vs 1 game, whcih is that we tend to fall back to.

But we're all enjoying learning the game and playing it, and look foward to our next games night.

The largest ship is larger than many of the celestial bodies you send it to fight over. The only reason the ships don't get bigger is because you wouldn't be able to afford them. Seriosuly.

Would always go to a friends house and a bunch of us would set up a LAN. Would get to the point where we would create great armies and vast trade networks all with wispers of alliances and aprisings. Then when when things got to a point where every star had been claimed, battlelines drawn and 8 hours of preparing for a massive war... and i would fall asleep and get wiped out by my friends for my resources.
10/10 Would fall asleep again.
