Elements of War

Elements of War is a real-time-strategy (RTS) game unlike any other – where players' armies manipulate the forces of nature to rain down destruction on thier foes or gain a tactical advantage by transforming the battlefield. Set on Earth in the not-so-distant future, Elements of War focuses on a conflict for the survival of humanity that ensues after a secret military weather control experiment sets in motion a near-complete global climate collapse. Three factions battle on American soil for control of fearsome weather-based weapons, granting them the power to use tornados, hurricanes, earthquakes, torrential rains and other forces of nature as weapons of war
