Paradox Interactive announces a May 28th release date for Crusader Kings II: The Old Gods, the Crusader Kings II expansion in development at Paradox Development Studios. A new trailer celebrates the news with the first look at gameplay from this fourth add-on for the strategy sequel. Here's the deal:

NEW YORK – April 24, 2013 – Soon Paradox Interactive and Paradox Development Studios will welcome you to a past darker than you can imagine, where there are few shining knights or mighty castles and the kings of Europe are more petty warlords than imposing rulers. We stand only 400 years from the fall of Rome, and a mere 200 from the revelations of Mohammed and much of the world still clings to an ancient code written with iron and blood.

This is the world of Crusader Kings II: The Old Gods, and it is yours for the taking on May 28.

The latest trailer for The Old Gods is the first trailer to show gameplay from the expansion. Feast thy eyes on river-going vessels, the new map and brand new powers that will compete for prestige and prominence.

The Old Gods is the fourth full expansion for Crusader Kings II, Paradox’s critically acclaimed strategy/RPG of medieval scheming, dynastic fortunes and crusades against the unbeliever. The Old Gods expansion lets the player start two hundred years earlier than the Crusader Kings II base game, at the height of Viking power and when the light of Christianity had yet to penetrate many of the dark forests of the continent, and the power of Islam was still on the rise.
