Paradox Interactive announces an October 30th release date for the Art of War expansion for Europa Universalis IV, invoking Machiavelli's inspiration, rather than Sun Tzu (though the latter famously wrote, "when your opponent expects a sequel, release an add-on"). A new video developer's diary celebrates the news with a look at some of the tools this will add to the player's arsenal in the game. Here's more on the expansion:

"I reply that since war is not a job at which any man can make an honorable living, it should be left entirely in the hands of princes or governors." – Machiavelli, Art of War, Book I.

Paradox Interactive today announced that Art of War, the newest and largest expansion for the award-winning grand strategy game Europa Universalis IV, will be available worldwide on October 30, 2014. This, the fourth expansion to be released for Europa Universalis IV, adds a vast array of changes to the game at the fundamental level, including a dramatic overhaul to the game map itself.

To mark this announcement, we have a new video dev diary, where Martin Anward who is Project Lead for Europa Universalis IV explains some of the new tools available to players as they march to war. Learn about new diplomatic options, the new powers of rebels and other notable changes.
