Halcyon is the Solar System in which The Outer Worlds takes place. Halcyon is far away from Earth in the frontier of the colonized galaxy and is the target of development projects by massive corporate conglomerates.

Halcyon in The Outer Worlds

Halcyon is a Solar System comprised of two planets, several moons, and asteroids.

Several Space Stations are also found in this area, and are sponsored by some of the Factions or are simply private ships



Locations in The Outer Worlds refers to the many areas that players may explore within the game. In The Outer Worlds, players can expect to explore two Planets (that we know of), several space stations and asteroids within a distant Solar System. Areas open up as players complete Quests and unlock them with in-game actions. These locales will have limited level scaling, so adventurers should be careful not to venture forth into certain locations until they are ready for the challenge.
