Inspired by the events of the era, particularly the Gulf War, the team gave the game a modern warfare setting. Westwood conceived Command & Conquer during the final stages of the development of Dune II, and it expands on ideas explored in that title. The groups compete for control of Tiberium, a mysterious substance that slowly spreads across the world. Set in an alternate history, the game tells the story of a world war between two globalized factions: the Global Defense Initiative of the United Nations and a cult-like militant organization called the Brotherhood of Nod, led by the mysterious Kane. Command & Conquer (also known by the retronym Command & Conquer: Tiberian Dawn) is a 1995 real-time strategy video game developed by Westwood Studios and published by Virgin Interactive.
