The World Undone: 1914 Serbia covers the ill-fated Austro-Hungarian invasion into Serbia at the beginning of the war. An overwhelmed but experienced and and aggressive Serbian army quickly made short work of 3 invading Austro-Hungarian armies during an operational campaign set in dense terrain with frequent counter-offensives. The Austro-Hungarian forces were ultimately routed and would not return until they had the help of Germany and Bulgaria. Units are Divisions and smaller. Turns are 1 day. Each hex is approximately 7.2 km.
