Wipe out every enemy platform and builder ship (skirmish) or complete the mission objectives (campaign).
The sector is a network of star systems connected by wormholes. You watch one system at a time – the sector map (top right, Tab for the big one) shows all of them. Right click a wormhole to jump through it; right click a system on the sector map to send your ships there.
Three resources: ore, gas and crew. Harvesters mine ore and gas from planets, asteroid fields and gas nebulae and bring it to a Refinery (or the Command Hub). Habitats recruit crew from a planet's population. Planets slowly regrow.
Every ship costs command points. The Command Hub gives 16, every Habitat 10 (max. 150).
Select a Fabricator, press B and click a free orbit slot around a planet. Big platforms need two slots. Gate Locks are built on a wormhole and stop every enemy ship from passing it.
Every shot uses supply (blue bar). Ships without supply cannot fire! They refill near the Command Hub and Repair Docks, or from a Supply Tender that travels with the fleet.
A Flagship / Hive Queen makes nearby ships stronger. The Research Lab unlocks upgrades and capital ships. Troop Carriers / Infesters capture enemy platforms whose hull is below 50 % – even enemy shipyards, which then build enemy ships for you.
