Crusader Kings 2: Horse Lords is an add-on for a global real-time strategy game. The addition reveals the full potential of nomadic peoples — the Mongols and other tribes received their own gameplay features. Also, the game map has been significantly expanded due to the annexation of China and other lands in the east: the famous Great Silk Road has appeared in the game. To develop, nomadic peoples will need to be in constant war and expand their possessions, because a huge army must be maintained.
The add-on requires the original version of Crusader Kings 2.
