Interstellar Dominion is an open world game set in space. Two factions are at war, the Vanguard, and the Empyrean. The actions you take will determine what faction you belong to. As if this wasn't enough of a mess pirates are out looking to turn any ship they see into scrap to sell.

Contracts can be started by locating faction owned planets, this is where you can earn credits.

These contracts include:

• Delivery: Transport material to a nearby ship.
• Escort: Guide a ship to a location while protecting them.
• Bounty: Eliminate a nearby ship.
• Convoy: Stop and destroy a convoy delivery.
• Planet Discovery: Find a planet you have not previously visited.
• Planet Destroy: Destroy the defence systems of a planet, and fend off their ships.
• Mining: Mine asteroids for material.
• Capital Destroy: Destroy a capital ship belonging to the opposing faction.
• Recruitment: Find and add a civilian ship to your squad.
• Resource Stoppage: Destroy a set amount of miner class ships belonging to the opposing faction.
• Resource Theft: Mine any planet owned by an opposing faction.

Who you work for, who you attack, and who you help is tracked and represented with a faction level. Show loyalty to a faction and your level will increase, this leads to better contract payments, and their ships will be willing to join your squad and help in combat. Work against your faction and your level will decrease.

Upgrade ship parts, each with different stats and uses, such as shields, thrusters, tracking, and more.
