Stellaris Overlord

Stellaris Overlord is an expansion for Stellaris about expanding your empire’s influence across the galaxy. You can specialize vassals, bring scattered empires under your rule, and build megastructures and other technologies to project your power.

Shape your vassals

New vassalization mechanics let you define the roles of your subjects. You can create Specialist Empires focused on becoming economic superpowers, military specialists or technological creators, then negotiate or demand contracts and agreements between vassals to shape the future of dozens of worlds and reap benefits.

Meet other empires

As you explore, you encounter more enclaves, including mysterious shroudwalkers, militaristic mercenaries and crafty salvagers. You can pursue mutually beneficial relationships to gain their unique services or seek to bring them under your rule by force.

Five new origins

• Imperial Fiefdom: Begin as a Specialist Empire with the possibility of becoming the galaxy’s ruler.
• Slingshot to the Stars: Discover the ruined remains of a Quantum Catapult near your homeworld and investigate what it can unlock if you restore it.
• Subterranean: Lead a species adapted to life underground, with strengths in mining and archaeology, and explore what lies above the surface.
• Teachers of the Shroud: Develop in contact with the Shroudwalkers, curious psions who teach your empire about expanding its mind.
• Progenitor Hive: Lead a hivemind that can achieve more under your guidance, but will fall into ruin without it.

Project your power

New technologies help your empire pursue dominance across the galaxy. Orbital Rings extend your influence and defenses from your planets into space, while Hyper Relays let your fleets enforce your will across the stars faster. Quantum Catapults offer another way to respond quickly and project your might, but sending a fleet through one is a daring one-way trip. The expansion also adds four music tracks.
