“Endless Space is smart, polished and intelligent game of countless permutations. Its strength lies in how carefully and how cleverly it's balanced, as well as how it rewards all kinds of playing styles. We haven't seen a strategy game quite like this in a while.”
8/10 – IGN

“In case it's not yet clear: go for it. If you are an experienced player, go for it. You are rather inexperienced with the 4X genre and it frightens you? Go for it.”
9/10 – FactorNews

“For a first game, it is surprisingly complex, demanding and motivating.”
82% – GameStar

About This Content

Disharmony brings a brand new experience to Endless Space players. A new faction with a unique play style, “The Harmony”, will make its appearance. Battles will be even more intense with the addition of fighters and bombers, battle formations, a new targeting system, a redesigned weapon system and enhanced invasion mechanics. The AI opponents will be significantly more unpredictable with the implementation of the new ‘Adaptive Multi-Agent System’. Prepare your empire for epic space battles!


The Harmony had been moving since the birth of the universe, passing through the galaxies, seeking The Core. Their migration was deliberate, calm, inevitable.

Dust was their downfall. In the galaxy of the Endless they were ensnared; this strange technological creation that affected particles, fields and waves broke the single movement of the Harmony into a cacophony of gravity-enchained individuals. The Harmony sees Dust as a menace or a plague, and has set out to rid the universe of its effects.

For the rest of the galaxy, this cleansing is a minor apocalypse. The Harmony, creatures of mineral, see no difference between "inhabited" and "uninhabited" planets -- they are simply "infected" or "clean." And those that are infected will be dealt with ruthlessly…

The Era of Disharmony has begun!


  • A brand new Faction called “the Harmony” with a single objective in mind: Annihilate Dust!
  • New Fighter and Bomber units that will completely change the shape of combats, especially with the new Battle Formation and Targeting systems
  • A complete rework of the Ship Design interface, including an improved Weapon System that provides family types for modules (melee, medium range and long range)
  • New Invasion mechanics have been added: Prepare your population for Bombardments, Sieges and land Invasions!
  • Expect to face a real challenge when playing against AI opponents with the New Adaptive Multi-Agent System (AMAS)
  • Many other additions and features voted or requested by the community including such as 4 new Heroes or a new option to disable Exchange of Technologies

Disharmony is an excellent expansion pack to a fantastic game that adds a lot of things that were missing from the base game, the one problem I have with Disharmony is the Harmony themselves, they aren't properly balanced with the other races and tend to be drastically weaker than everyone else.

Somehow they took endless space and made it better. With the inclusion of fighters, increased combat depth, as well as some slight changes in game mechanics, no longer will you feel like combat is just a matter of auto resolving. If you liked the core game at all, you gota get this expansion!

I wouldn't play the game without it honestly, I know some people got the base game via the Humble Bundle...

Not only does it add a faction, it changes several others that were originally just reskins; it COMPLETELY changes the combat mechanics, the ship editor is different, lots of stuff :x

I make this review mainly to bring that to people's attention; in all honesty, the game should've gotten some of this stuff without having to pay for it so I hate to give it a thumbs up, but yeah, if you want to like this game, get Disharmony :>

This was previously posted as a review under the Endless Space - Emperor Edition. Oops.

First of all, I'm writing this as I listen to the ES soundtrack which comes with the Emperor Edition. Really enjoy it. As for the game, well...

I downloaded the two Amplitude titles, Endless Space (Emperor, with Disharmony, etc) and Endless Legend at the same time. Started playing EL first. And it's a good way to learn the Amplitude FIDS system (Food, Industry, Dust, Science). Dust = money in the Endless worlds. It introduces the world of the Endless, Auriga, which makes an appearance in ES Disharmony. Disharmony is what I'll review here; it's newer, better and has a faction you may want.

- Good looking game.
- Great sounding game.
- Fairly flawless play system (a couple of hangs in 80 hours, I can live w/that).
- Enough factions and options to make almost any custom setup you want. And you WILL want a custom faction if you play this for very long. A bunch of galaxy styles? Yes, please. Random galaxy and system events keep things non-linear early, as do, uh, pirates. Yeah, pirates.
- Disharmony has tie-ins to the Endless Legend game, so if you have played that, it feels more complete. Auriga, the Vaulters, probably a few other aspects I've missed. No pushy super-diplomats like the Drakken in EL, thankfully.
- If you miss the old MOO games, this should fit the bill.

- In comparison with other 4x games, space and flatland both, this is probably the most aggressive universe I've played. Factions will go from Peace to War in not so many turns, if they think you can be taken on the battlefield. The result is a flurry of early shipbuilding by everybody, including the player if they want to get past 50 turns in w/o a war. No leisurely stroll through the stars here while you throw upgrade after upgrade onto your planets.
- Because of that, I have a hard time believing some victory conditions are doable. Namely the diplomatic victory. And diplomacy is fairly flavorless.
- The tech tree takes several playthroughs to understand to full advantage. And the tree in Disharmony is different from the one in the base ES game.
- I wouldn't say the AI cheats, but even on Normal difficulty, there is a noticeable difference in the nearby planets the player gets vs the AIs.
- Certain features are left either to accidental discovery or forum browsing to find out about (Ctrl-RightClick for fleet warp movement is one).
- Fleet management. Easy to add ships to a fleet, but to pull one or two out, seems like you have to select Disband and then put the fleet back together.

To win: So far, all I've won is a couple of games on Scientific Victory, with a custom faction based on the Vaulters; they have a jump/portal system improvement which brings back some balance against the pesky AI. In the research tree there is also a Wonder Victory (which may vary by faction?), but that requires research and then building it. You can win Supremacy by building ships from the get-go and taking out races before they do the same to you, not my personal style. Haven't made it to 300 turns which I'm assuming is the same default game end as EL; it's kill, be killed, or research the heck out of the tree and win that way, and most of that will happen well before turn 200. ES has few autosaves and no natural interval to save games at (vs EL, where every 20 turns you have empire decisions to make); I'd advise doing regular saves.

8/10. It's a nice clean space 4x game which will frustrate at first, but is fine once you get to know it. I'm 80 hours in and have just scratched the surface.

The visuals in this game are amazing. The planets are gorgeous, and the space battles colorful. The ship designer is cool, but is unlike the Gal Civ 2 ship designer. In Gal Civ 2 and other games, you can design the hull. In Endless Space, the hull (and therfore, the look) is constant. You can only modify what the ship carries (weapons, defenses, support modules, etc.). I really enjoy the heros, system strategy, macro strategy, and the game creation options. All in all, this is a very solid 4X game.

Endless Space is definitely a good game, and worth playing if you like 4X games at all. Ultimately though, the game was a bit bland gameplay-wise; the setting, factions and worldbuilding are very good, but battles aren't very interactive, sometimes seem to come down to a game of rock-paper-scissors, and there isn't much complexity to them.

This expansion helps, adding more depth to combat and a lore-based win condition that fits better with the lore than plain old conquest. But ultimately the gameplay still feels kind of anemic, though it's fun and you can certainly spend several full days on it.

Ultimately though, Endless Space and its expansion was really more of a prelude to the better (and fairly different) Endless Legend. Endless Space proved the devs could make a good, full-featured game, but it seems like they quickly moved on to their next, more ambitious project. Still, the game is a worthwhile purchase, and its expansion is cheap.

The DLC adds a few new things but unfortunately it breaks more than it adds. You can expect extreme load times (2 minutes instead of previous 10s), disappearing UI elements and even more random AI behavior. I just had an alliance with very friendly AI turn to war in one turn due to "high score" even though my score was dropping constantly.
The Harmony race is also a problem - they can 'purify' a planet so that it can no longer produce dust. The problem is that if you conquer such system it will work normally (produce dust) for dozens of turns until suddently the game goes "wait! it's purified, you can't produce dust here" and slams your dust delta from +70 to -1500 in one turn.
Also the fact that you cannot ever remove the dust impariment from the planet makes Harmony pretty much OP - once they conquer a system it becomes an endless dust drain for any other empire (it does not produce dust but it does cost dust to upkeep all the buildings). In the end if you play as Harmony and conquer a big part of galaxy it's nearly impossible to defeat such a player as it's too heavy a burden on dust to handle.

All in all like I said - it breaks more than it adds so unless you're fine with random sh!t happening randomly at any point, save yourself the nerves and keep to the basic version of the game. It just seems like they release it in beta stage...

If you own Endless Space, definately pick this up. Improves many aspects of the game; the main being combat. New factions are very interesting aswell and make for even more intense galactic conquest. For only $10 it adds much, grab it!

I usually hate DLC to the point of giving it an automatic negative review but that's mainly due to the way developers use it to scam more money from their fanbase. Disharmony is one of the exceptions, adding so much great content that it feels like a total upgrade of the original game. Worth the price.

Endless Enjoyment

Galaxies unfold before your very eyes, and you wonder where next to go.

Travelling the stars, you look for planets to call home, and encounter other space-faring species along the way. They could be cyborg seekers of truth and wisdom, or humanoid Dust-loving expansionists, or soulless robotic vessels sent out by the long forgotten Endless, razing world after world for finite resources … or so many others…

You have your own agenda, and exploit the colourful celestial bodies of every solar system as you see fit. Resource extractors rise from the planets’ crusts, ancient moon temples are uncovered, primitive and non-space-faring species are brought into the fold or used as food or slaves… the possibilities are endless.

Throughout the eons, your people will learn how to keep eternal peace, or reign supreme with an iron fist. They will cure all known diseases, discover mind-boggling technologies, build more sophisticated space ships to travel faster and farther, terraform any type of planet, and transcend life itself.

And in the end, someone or something will unearth the secrets of the legendary lost planet Auriga.

This is the Endless Space.

This… is your future.

TL:DR - They are rocky & glowing shard creatures with rocky & glowing shard ships who disable half parts of the game for a partial benefit. I think its pretty good

In my first and only game i used the harmony class without realising. it has some restrictions like no dust speedups, no retrofitting (annoying) and no heroes. Some of the benefits of them hating dust are good like no upkeeps and the ability to get certain stuff without dust. This is further improved by how when you get the dust conversion into other resources you can generate a small amount of resources instead of useless dust. (in the tech tree its in the weapons part so i didnt unlock it till fairly late game as i was upgrading the explorer part of the tech tree). There is no approval rating on planets which is awesome so you stop worrying about that. something slightly annoying is how whenever there is a random event that gives dust you get nothing but atleast whenever you make / improve something that requires dust you get it for cheaper....

The loading times between turns felt too long and there was a minor memory leak i think as it started to be slower after i played for over 15hrs without closing it.
