Command & Conquer 4: Tiberian Twilight is an upcoming real-time strategy game and the latest installment of the popular Command & Conquer franchise currently under development by EA Los Angeles exclusively for Microsoft Windows and is set for release in 2010. It will constitute the final chapter in the Tiberium saga. A cinematic trailer for the game was released on July 24, 2009 with many more details revealed in magazines which featured extensive cover stories on the game. In addition, Command & Conquer 4 will require the player to be online at all times regardless of whether the player is playing single player campaigns or skirmishes or online play, however EA is currently considering whether to create an offline mode for players to play the Campaign offline. Command & Conquer 4 will also utilize EA's own servers for online play, rather than Gamespy Servers, which EA has relied on for Command & Conquer games in the past.
Tiberian Twilight is the final game in the Tiberium Story Arc, which began in the year 1995, and has a sterner and more mature tone compared to previous games. The game begins in the year 2062, 15 years after the events of Tiberium Wars which led to the invasion of the Scrin and 10 years after the events of Kane's Wrath. In this time period, Tiberium has advanced to the next evolutionary stage and is rapidly spreading across Earth, expected to become uninhabitable by 2068.
At this time of crisis leader of the Brotherhood of Nod Kane heads straight for the headquarters of the Global Defense Initiative, in hopes of forming a "Tiberium control network", which would allow the spread of Tiberium to be controlled, as well as turn it into an inexpensive power source. The campaign starts 15 years after the formation of the network due to a temporary alliance between the two factions, however extremists of both factions cause unrest, which sparks the Fourth Tiberium War ending the alliance. Tiberian Twilight will complete Kane's story, revealing his identity and motives. The Tiberium Universe is planned to continue beyond C&C 4.
