Crossplay

Is Pathfinder: Kingmaker - Definitive Edition crossplay?

Crossplay does not apply to Pathfinder: Kingmaker - Definitive Edition: it has no online multiplayer.

The Definitive Edition will have all of the DLC from the PC version of the game, including Beneath the Stolen Lands, Varnhold's Lot, and Royal Ascension. The console version will include a turn-based mode, which has been present in the PC version via mods.
