Tiberium. The infamous green crystal that destroys entire worlds in its wake of global proliferation. It has been a little over a century since the Tiberium threat was first wiped out on Earth, and with it, the primary vestiges of the Brotherhood of Nod. When the GDI advanced humanity to the stars, they found that Earth had not been the only target of the alien Scrin: dozens of other worlds had already been claimed by Tiberium, and the Scrin returned in full force, attacking human colonies across space, stopping human expansion. To fight back, the GDI undergoes a reformation to become the Interstellar Defense Intiative (ISDI) and enacts the Hallman Directive, designed to stop Tiberium spread wherever it may be; such a protocol brings the reincarnated ITC Methuselah to a planet being ravaged by the green crystal, and the forces under Commander Martin Alexandra deploy to stop the threat.
