01 / Establish your world
Your capital is the foundation of your strategy. Develop production, collect resources, research technology and build the ships your next move needs.
Your capital cannot change owners, but attacks can still hurt. Colonies expand your reach as you progress — and rivals can capture them. Expansion creates opportunity and something to defend.
Worlds & development
02 / Read the unknown
Rival holdings are private until you discover them. Use radar warnings, telescope observations and probe reports to turn an unfamiliar galaxy into decisions you can make.
A report is a reading from a moment in time. Compare what you know, what may have changed and the risk of sending ships before committing your fleet.
Intelligence & discovery
03 / Commit your fleet
A fleet is more than its attack strength. Ship roles, cargo space, fuel and travel time shape what it can accomplish. The slowest selected ship sets the pace.
Raid for resources, transport supplies or contest a colony. Flights keep moving while you are away. Return to battle reports, new information and the consequences of your orders.
Fleets & combat
04 / Find your people
Clans turn individual plans into shared strategy. Coordinate in clan chat, send resources and station your own ships as support on an ally’s world.
Joint attacks assemble at the leader’s capital before departure. Once launched, a joint attack cannot be recalled. Preparation and communication matter before the fleet leaves.
