Paradox Interactive's highly complex strategy game Crusader Kings 2 is now available on Linux, the developer announced.

The SteamPlay enabled game is unlockable for PC, Mac and now Linux as long as the user already owns the title on one of the platforms. The game, set during the high and late middle ages, launched last year and was followed by numerous expansions and DLC including the recently release Republic add-on which centers around the mercantile republics of Crusader Kings 2.

Paradox is also currently teasing new content on its official Facebook page, with the release of a partially-revealed image and the caption "Day One."
