A game for Ludum Dare 32 "An Unconventional Weapon" about breaches of the Geneva Convention.
In the Hague Conventions of 1899 and 1907, the use of dangerous chemical agents were outlawed. In spite of this, the First World War saw large-scale chemical warfare. France used teargas in 1914, but the first large-scale successful deployment of chemical weapons was by the German Empire in Ypres, Belgium in 1915, when chlorine gas was released as part of a German attack at the Battle of Gravenstafel.
