Gameplay

• 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.

Triage

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?

Events

You'll encounter ships under distress, desperate refugees, greedy merchants, wreckage and caches to loot, shipyards and stations, enemy traps... and much more in over 400 hand-crafted events.

Politics

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

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.
