Story
In the year 2062, humanity found itself on the brink of extinction. Tiberium, the mysterious, alien crystalline structure that infested Earth for decades and caused years of relentless conflict between the Global Defense Initiative and the Brotherhood of Nod, was close to rendering the planet uninhabitable. In the midst of this crisis, Kane, Nod's prophetic leader, emerged from seclusion to deliver GDI the message that he had developed a system that could control Tiberium and harness its power. But he could not build this "Tiberium Control Network" without GDI's cooperation. Thus, the two opposing factions—GDI and Nod—found themselves in a desperate and unlikely alliance to stop Tiberium from extinguishing mankind.

Now, after 15 years, the network is nearly complete. Tiberium is under strict control and the revitalized Earth is on the cusp of a new age of prosperity and progress. It is only now that the world's citizens begin to seriously ponder why Kane chose to help, and what he will want in return. Kane. GDI. Nod. Tiberium. How will it end? These questions and more lead to the dramatic final act of the 15-year Tiberium saga in Command & Conquer 4: Tiberian Twilight.

Gameplay
Command & Conquer is a real-time strategy gaming franchise, and Command & Conquer 4: Tiberian Twilight is no exception. Players assume color-coated versions of the GDI or Nod factions and uncover segments of the map, where they must manage Tiberium and other resources in their possession or that they they mine or commandeer in the field. Other factions occur in the game, but are not playable, and different single player campaigns are available to players depending on which of the two factions are chosen. The energy that Tiberium crystals possess is used in the manufacture and upgrading of mining and combat units, weapons and support infrastructure in preparation for impending conflicts with other players on the same map that are doing the same. Each faction has its own distinct unit types, both land and air based, which although unique, are overall more or less balanced against those of opposing faction. In addition, certain units can be captured on the battlefield and used to supplement your arsenal. The overarching task though is to combine the right number and type of units with the right battlefield strategy for the conflict and terrain at hand.

Historically, C&C matches have been won by completely eliminating all enemy units that stand against you. Although there is certainly plenty of this within Tiberian Twilight, the game also is different in that players need not eliminate all enemy units, instead capturing control nodes throughout the game and holding them for a minimum amount of time. Doing so leads to earning enough points to win the match. Tiberian Twilight also differs from earlier games in the series with the addition of certain RPG game elements. Players overall orientation within their chosen faction is class based, with units falling generally in offensive, defensive or support classes depending on your play style. These units can be upgraded with experience points, which are gained through success against enemy units, with more advanced enemy units earning the conquering player more points, and thus potential unit upgrade opportunity.
