Stellaris: Willpower

Ideological expansion

Stellaris: Willpower is DLC for Stellaris on PC, adding Ideologies that let you spread your empire’s Ethics across the galaxy. You can broadcast an Ideology through Starbases, Hyper Relays and Ideological Beacons. Foreign populations may adopt it and form Fanatic Factions inside other empires, while colonies in your own empire can radicalize if your authority weakens or you stray from your values.

Influence and diplomacy

A relocatable Galactic Hall gives an Ideology a presence above a colony, where it strengthens local output and Ideological Reach, or at the frontier, where it carries the message into contested space. There’s a design for each Ethic, including a biological one.
