Tech Core introduces the rules for tactical starship combat, but GMs running a campaign with starships might consider exploring a few additional resources. GM Core includes the cinematic starship scene subsystem, which you might use to resolve a dramatic chase or an encounter with obstacles to overcome instead of enemy starships to blow up. Starfinder Galaxy Guide is a data-packed primer for the Starfinder setting, introducing many places a crew might explore in their starship, and Starfinder Absalom Station: Center of the Galaxy provides an excellent kickoff point or home base for any starship campaign—remember, even at the edge of the Universe, Absalom Station is always as close as the nearest Drift beacon.
