Stardeus Diplomacy arrived in Update 0.15 with a dedicated faction screen, alliances and more consequences for trading, mining and ship combat. You can now manage relationships through Ship Computer > Apps > Diplomacy.
Check the faction relationship before you trade, mine a claimed deposit or join a battle. Those decisions now affect prices, reinforcements and whether another ship sees you as an enemy.
Where to Find the Diplomacy Screen

Open Ship Computer > Apps > Diplomacy. This screen was added with Update 0.15 and puts faction relationships and alliances into one place, alongside other Ship Computer management tools.
Use it to check who is friendly, neutral or hostile before choosing where to trade, mine or travel. Reputation is now more than background information because ships react to your relationships.
Stardeus Diplomacy and Faction Alliances
The new system allows factions to form alliances. Positive relationships can affect which ships support you, including law enforcement officers helping you against pirates in ship-to-ship battles.
When you encounter an ongoing ship battle, you can join either side. Your choice affects the factions involved, so check the combatants before intervening.
Stardeus Diplomacy: Trading and Factions
Prices depend partly on your standing with a faction. Ships, stations and spaceports sell supplies, while the Stock Market reflects wider supply and demand. Better relationships can help your access to useful trade.
Stardeus Diplomacy also affects how factions respond to gifts and requests for assistance. Hail ships to interact, and use the Diplomacy app to see the wider relationship behind an individual exchange.
Owned Deposits and Mining Disputes
Resources in space can belong to a faction. Mining an owned deposit has consequences, and the changelog says ships belonging to that owner may attack if you take resources without permission.
Before you mine, check whether the deposit is claimed by a faction. Taking their resources can provoke an attack, even if you were on good terms before the expedition.
Stardeus Diplomacy During Ship Combat

Relations influence reinforcements, raids and hostile reactions to combat. Friendly NPC ships can join a player’s battle, while another faction may view your attack as a reason to retaliate.
A pirate fight is a good example of why allies matter: law enforcement may help against pirates. Choosing to attack a neutral trader, on the other hand, can cost you more than the loot is worth.
Sending Guests Home for Rewards
Rescued survivors belonging to friendly factions can remain aboard as guests. The update gives players a way to send them home for a payment and improved faction standing.
Your Stardeus Diplomacy options therefore include peaceful ways to improve relations while exploring derelicts. Treat rescued guests differently from hostile boarding parties, and check their faction before choosing a response.
Rogue AI Choices and the Virus Faction
Installing Asimov’s Override permanently allies the Ship Computer with the Virus faction. That relationship cannot be undone by removing the upgrade, because the Override itself is irreversible.
Stardeus Diplomacy is therefore linked to long-term research choices. Elysium also makes the Sentinels hostile and blocks the normal colonisation goal, so plan your faction relationships before committing to that path.
Stardeus Diplomacy: Best Ways to Manage Factions
Check the Diplomacy app before approaching a busy sector, trading or mining owned deposits. Trade where your standing is favourable, send friendly rescued guests home and consider who will back you up in combat.
As the ship grows, choose whether you want stable trading relationships or a more hostile route through Rogue AI technology. The same weapons and resources can produce very different outcomes depending on how other factions regard you.
