Command & Conquer™ 4 Tiberian Twilight

This title includes Steam Workshop support for User Maps. The setting is 2062, where humanity stands on the edge of extinction. Tiberium, a mysterious alien crystal that has infested Earth for years, is the main cause of conflict between the Global Defense Initiative and the Brotherhood of Nod and is about to make the planet unlivable. As mankind faces its doom, Kane, the prophetic leader of Nod, reappears to offer GDI a solution involving a system to control and harness Tiberium. Features include The Spoils of War, where destroying enemies grants experience points to upgrade your faction and unlock weapons; Choose Your Class, allowing you to command more units than in previous titles by selecting Offense, Defense, or Support classes with specialized abilities; and Always on the Move, introducing the Crawler, a mobile base that allows for redeployment across the battlefield for strategic advantages.
