In the end of Tiberium Dawn, Kane was reported missing, but his body was
never found. He became a legend.
Tiberium sweeped the planet, as it
expands through every piece of land. Only poles and a few areas stay clean,
and space stations start to be deployed.
One day, all of a sudden, the classic skirmishs get deeper, and battles
start everywhere. Kane is once more in front of Nod: He never really died.
GDI runs against time to stop Kane´s action, while Nod bases itself
on followingtheir leader, across twelve campaign missions, which include
securing a crashed alien ship, allying wth mutants and more.
