The Cossacks are set to take over Europa Universalis IV

Just when you thought you'd got a handle on the grand strategising required to prosper in Europa Universalis IV, Paradox usually goes and releases another game-changing update-expansion combo.

This time it's the Cossacks that are set to take over the publisher's historical strategy game. As per usual the new content will drop alongside an update that's available to all for free, but there's going to be plenty of new features coming to the game in the expansion. Here's the main details, and the new announcement trailer.

• New Diplomatic Options: Let the world know what you think of your neighbors by setting a public attitude to foreign powers.
• Tell The World What You Want: Designate neighboring provinces as "places of interest", build trust with other nations, and entice allies with the promise of land for their support.
• Tengri: Tengri is now a Syncretic faith, allowing it to tolerate a secondary religion as if it were a national faith.
• Horde Unity and Razing: Nomadic nations now must pay attention the horde unity of their tribes - a unity that can only be maintained by the occasional pillaging
• Improved Culture Change: You can now restore a previous culture to a converted province, or convert a province you hold to a culture that is not your own.
• Native Policies: Set your policy for colonial encounters with natives. Are you focused on quick subjugation, peaceful growth or trading advantages?
• Improved Espionage: New spy actions allow you to study the technology of more advanced countries and prod your rivals' subjects towards independence.

Earlier, during the summer, we took a closer look at EUIV to mark its two years spent out in the wild, for more on that head this way.
