You will choose from a variety of 8 unique factions with two additions, Conflux and Empire, (still in development by TQ Digital), develop elaborate castles that dominate the skyline of bustling metropolis, Harmondale, plunder resources in exhilarating missions and fortify your armies against the inevitable wars of domination that lie ahead. The closed beta will commence on May 7th, 2010 - the latest game client and a trailer have been added in our download area.
