What the developers have to say:

Why Early Access?

“As veteran developers we know the value of community feedback. Since we Kickstarted the game in 2015, XO has been in full time development. We've shown XO at numerous events like PAX and IndieGameCon, and went through a very collaborative alpha and beta phase with our Kickstarter backers before coming to Early Access.

Now we want your feedback. Help us shape XO!”

Approximately how long will this game be in Early Access?

“We will release when we feel it is ready.”

How is the full version planned to differ from the Early Access version?

“With your input we plan to add content, new ships (with new actions), and expand the event system to allow for even more complex and interesting events.”

What is the current state of the Early Access version?

“The game is fully playable, with over 30 ships, 500 events and 10,000 words of narrative. A successful run takes several hours to complete.

XO's universe is procedurally generated but the events are hand-crafted, making a dynamic experience that never plays the same way twice.”

Will the game be priced differently during and after Early Access?

“We plan to increase the price as we add new content and features. We have already raised the price once, we do plan on raising it again before release. We will communicate these early to the community. By joining us in Early Access you will always have access to the full game!”

How are you planning on involving the Community in your development process?

“We've learned a lot about transparency and frequent updates during our Kickstarter and subsequent alpha and beta release. For many months we have been publishing regular updates to the game with extensive notes. Our Discord is where the community votes on upcoming features and makes suggestions, and we will continue to provide active support through the Steam forums here as well.”

About This Game

Congratulations, you've just been given command of the galaxy's finest battleship. Well, it would have been, if it had been completed. Your first mission: find some weapons!

In XO you must gather the remains of humanity, build a fleet, and try to stay ahead of the relentless Harvesters. Each ship you add to your fleet gives you powers but also reduces your dwindling resources. Who will you choose to survive?

If you keep moving, you might just stay ahead. Yes, you're going to need that pause button.

So, how will you command in this time of chaos? By seizing cargo, weapons and ships, or through diplomacy and sacrifice? You decide who lives and who dies, because without you, there is no hope for humanity.

Every game plays different based on the command decisions you make.

Original soundtrack by Jim Guthrie


  • Emerge from jumpspace near a planet where you will begin rescuing survivors, scouting ahead, and defending against ever-stronger waves of enemies until you judge it is time to evacuate the fleet.
  • Navigate treacherous political scenarios in a time of upheaval as the war brings out the best and worst in people.
  • Choose the next planet to jump to based on limited intel, taking into account the resources you need, reported enemy strength, and refugees at each possible destination.
  • Spin up the fleet's jump drives and lead your able ships to the next planet.
  • Resources are automatically gathered, but the ships in your fleet influence your gathering rates and capacity -- as do different planet types.
  • Use your resources to upgrade ships, manufacture weapons, and make critical repairs.
  • Hope you have the right ships and enough resources when the enemy finally closes in.


You won't be able to save everyone. As fleet commander, it's your job to make the call: do you save the damaged military destroyer to add more firepower to your fleet, the tanker that will extend the fleet's range, or rescue the farmship capable of producing enough food to keep your people alive?


You'll encounter ships under distress, desperate refugees, greedy merchants, pirates, wreckage and caches to loot, shipyards and stations, enemy traps... and much more in over 600 hand-crafted events.


You are faced with a fractured political landscape where five factions squabble and fight. Your actions will have a direct impact on the relations between the factions. Do you try to unite them all, take sides, play them against one another or shoot first and ask questions later?

Each situation you encounter will require thoughtful leadership. Demands, urgent calls for help, and interesting opportunities will present themselves, often at your most trying moments.

Faction leaders provide you additional political tools including intimidation, diplomacy and haggling.

Combat, Weapons and Movement

The action takes place in close orbit around planets. Ships fly on a 2D plane; inertia acts against ships. Acceleration/deceleration, turn rates and weapon ranges make a difference. Custom formations allow you to make the most of your offensive and defensive capabilities. Warships can be issued Rules of Engagement (ROEs) limiting their combat actions.

There are several types of weapons at your disposal, lasers, missiles, mines, shields and the devastating nuke.

However, one does not enter combat lightly; weapons drain your precious resources and can even delay your ability to jump away.


Resources are plentiful; time, however, is not. In order to keep your fleet going, you'll need water, fuel, and ore. Collection is automatic, but the time it takes to collect what you need may require the sacrifice of hundreds of brave souls. Wily and creative captains may also find these resources at space stations, depots, and aboard abandoned starships.

  • Fuel: Easiest to find. Used for nearly everything, from laser weapons and shields to the powerful jump drives that fling you between stars.
  • Water: Somewhat common. Used primarily for factory foodships that feed the fleet.
  • Ore: Slowest to obtain, somewhat rare. Used for repairs, upgrades, missile-type weapons... and bribes.

Your exodus will take you to many worlds. You'll come across habitable worlds, gas giants, airless rocks, frozen wastelands, and hellish molten planets. Each can be tapped for the precious resources you need to survive... provided you have the right ships in your fleet.
