Set in the 5th century BC, the ancient world of Greece is in turmoil, under threat from Xerxes and his giant Persian Empire. This is a world where politics and diplomacy prove as sharp as the blades of combat. Few men have dared to rise against Xerxes and his invading armies. The people need a hero – someone to stand up and unite Greece in the battle against his empire. With guidance from King Leonidas and help from his Spartan army, you will hone your abilities as a strategist, diplomat and a leader, while you build an army unrivalled by even that of Xerxes. Sparta: War of Empires is a MMO strategy video game developed and published by Plarium. The game was released for web browser in 2014. The game is available free, with paid upgrades available.
