Electronic Arts today announced that Command & Conquer 4, the latest installment in the popular RTS series, has shipped to retail worldwide, exclusively for PC. The story takes place after the events of Command & Conquer 3: Tiberium Wars. The year is 2062 and humanity is at the brink of extinction. With only six years left until the mysterious crystalline structure Tiberium renders the earth entirely uninhabitable, the two opposing factions – Global Defense Initiative (GDI) and the Brotherhood of Nod – inevitably find themselves in desperation for the same cause: to stop Tiberium from extinguishing mankind. In addition to the two campaigns on the epic battles of GDI and Nod, which players will get to conquer alone or in a cooperative mode, Command & Conquer 4 will also feature a new 5v5 objective-based multiplayer mode, promoting teamwork and cooperation.
