Command & Conquer 4: Tiberian Twilight
The prologue takes place in the year 2062, 15 years after the Tiberium Wars (which led to the invasion and defeat of the Scrin), and 10 years after the end of Kane's Wrath (where Kane regained possession of the Tacitus). Tiberium has evolved and is spreading at such a rate that the whole planet is expected to become uninhabitable by 2068. Humanity is on the brink of extinction.
At this time, the leader of the Brotherhood of Nod, Kane, heads directly to the headquarters of the Global Defense Initiative, in hopes of using the Tacitus and GDI's resources to construct a worldwide Tiberium Control Network. This network will allow the spread of Tiberium to be controlled and turn Tiberium into an inexpensive power source. Even though the idea of alliance has been met with hostility (which has sparked the brief Incursion War), the two factions have nevertheless united. The campaign itself starts 15 years after the formation of the alliance, as the Tiberium Control Network nears completion. The spread of Tiberium is finally stopped, bringing optimism to the world's remaining population. However, extremists from both factions start to cause unrest, which sparks the Fourth Tiberium War.
The player takes the role of Commander Parker, a GDI military officer who receives an optical implant after his battle wounds have caused him to lose his eyesight. The player is presented with the possibility to aid either Colonel Louise James's GDI extremists or Kane's Nod Loyalist forces in the Fourth Tiberium War.
The game's missions chronicle Kane's attempt to activate the Threshold 19, a tower constructed by Scrin aliens during the Third Tiberium War that functions like an interstellar portal. He claims to have used the Tacitus to help create both the Tiberium Control Network and the optical implants; these are, in fact, the keys to the activation of the tower. While the GDI and the Nod finally form an alliance, two groups of separatists desperately try to spark a war to stop (or punish) Kane. The madman Gideon leads the Nod separatists, while Colonel Louise James commands the GDI.
After the final battle for the Threshold 19, Kane is about to leave Earth using the Scrin tower. He convinces Commander Parker (the player) to activate it for him with the optical implant. The player is shot by Colonel James but nonetheless succeeds in activating the portal. In both campaigns, Kane enters the portal. (In the GDI campaign, Kane promptly thanks the player before entering it.) In the ending cut-scene, news channels announce that the Tiberium growth has receded following the complete activation of Tiberium Control Network and all the Nod followers have entered the Scrin tower and disappeared.
