Build a fleet and lead humanity to safety. Grow your fleet using force, diplomacy or guile... and try to stay ahead of the relentless Harvesters. Each ship you add to your fleet gives you powers but also reduces your limited resources in this challenging RTS-with-pause game.
In XO you're on the run and must amass a fleet powerful enough to save humanity. Seize cargo, weapons and ships by force -- or use diplomacy and make sacrifices to gain trust among the factions. The choice is yours.

On each unique run you'll encounter ships under distress, desperate refugees, greedy merchants, pirates, wreckage. There are caches to loot, shipyards and stations, enemy traps... and much more.

Each ship you add to your fleet reduces your dwindling resources, but adds unique abilities. Warships add firepower, Farmships feed your fleet, Industryships add manufacturing, research and repair capabilities, and Cargoships increase your fleet's storage capacity.

As your fleet grows you must also navigate treacherous political scenarios. How will you deal with infighting, sabotage, and the misunderstandings that come from cramming together people of opposing factions? Do you rule with an iron fist, try to bring opposing factions together, favor a particular faction, or carefully manipulate the factions to keep a balance? You decide.

Use your resources to upgrade ships, create trade items, manufacture weapons, and make critical repairs. Resources are automatically gathered, but the ships in your fleet influence your gathering rates and capacity -- as do different planet types.


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