MoW is a true MMO RTS which is played completely in the browser window and requires no download ever, giving players the ability to play the game instantly anywhere.
The game has a feature which is unique in the world of browser MMOs: an Endgame. There are four civilizations in MoW: Rome, China, Egypt, and Persia. If one of them rises up and defeats the other three, the winning civilization will be declared a MoW Champion and the Realm will reset, with spoils to the victors. For this reason, there are no sidelines in Ministry of War. You must form strategic alliances and fight, or your empire and your entire civilization may be swept from the Realm. Each Endgame victory will form a chapter in the history of MoW.
