The Final Act

The Final Act is the final mission of the Nod campaign in Tiberium Wars, occurring in the region around Threshold 19 in Italy. The Scrin were attmepting to make the tower invulnerable to all Earth weapons but GDI launched an offensive to stop them. Eventually Nod were able to hold off the GDI assault long enough for the tower to become invulnerable.

Background
By this point in the war, GDI and Nod had both driven deep into the Italian Red zone. The main objective of GDI was to stop the construction of the Scrin's Threshold towers, while Nod was concentrating on capturing one for themselves. GDI's best battle commander had successfully destroyed a threshold in Rome, and other GDI commanders managed to follow that example. Soon, only one tower, in what used to be the Mediterranean, was left standing.

Nod directs their best commander to protect the tower for their own use. They discovered that the Phase Generators in the Scrin base were what was protecting the tower from GDI assault. Eventually the twoer would become invulnerable on its own. It was imperative that the generators be preserved long enough for the tower to become invincible. For this to occur, GDI must be held back and their forces destroyed.

Opposition
Nod faced heavy opposition from GDI, who occupied two bases in the region. For unknown reasons, Nod also received opposition from the Scrin, who will not hesitate to use their Rift Generator on the Nod base at any opportunity.
