A Real-Time 3D Strategy, Besieger is set in a medieval fantasy world in which rival players wage war as either Viking or Cimmerian warriors. As well as the bloody battles, each player must build, protect and attack fortified citadels. The easy economic system will allow players to construct or upgrade 40 types of buildings and more than 50 different units for battle. They will also 'create' and train workers for fighting and other survival skills.
