The Great War Approaches

It is 1913. Europe is a powder keg, bound by tangled alliances and fueled by industrial rivalry. As the leader of a Great Power, you hold the destiny of millions in your hands.

  • Manage Alliances: Balance the obligations of the Triple Entente and the Triple Alliance.
  • Modern Warfare: Navigate the shift from cavalry charges to machine guns and trench attrition.
  • Total Mobilization: Rapidly expand your army, naval tonnage, and industrial capacity before the clock runs out.
  • Win the War: Achieve total dominance by crushing enemy morale and securing key territories before your own home front collapses under the strain of total war.
