..::: ABOUT THE GAME :::..

Stronghold Kingdoms is the MMO successor to the Stronghold castle building series, famous for the original Stronghold (2001) and Stronghold: Crusader (2002). Relive the Middle Ages in the world’s first castle MMO! This cross-platform strategy game thrusts the Middle Ages into a persistent online world. Besiege castles, overthrow tyrants, bankroll your faction’s war effort, pillage your neighbour’s resources, peacefully raise cattle, or do it all! Only by engaging enemy troops, conquering territory, competing in Tourneys, and winning votes in the political arena can players hope to succeed.
