The Escape from Earth

The final assignment of the Legendary Insurgent in the Third Tiberium War was to secure the last remaining Scrin Threshold for the Brotherhood of Nod and prevent it from being destroyed by GDI. Operating from an already advanced base, Nod forces were tasked with the protection of three Phase Generators that shielded the tower-in-construction from any harm and obliteration of remaining GDI forces.

The Battle
In the first phase of the battle, Nod forces destroyed three Juggernaut walkers that were continuously shelling the Scrin base and secured them, gaining a valuable outpost in the field, which gave them excellent overview of the battle situation as it unfolded. In the meantime, Nod prepared an assault force as it fended off strong GDI assaults and relatively minor Scrin raids, as well as constructing the Temple of Nod.

With the nuclear missile being prepared for launch, Nod begun its assault on the GDI base, and as GDI forces attempted to concentrate their defences in the base, the nuclear missile was launched, effectively eradicating any kind of organised fight the GDI could put up.

The battle ended in full Nod victory.

Meanwhile, Foreman 371 protected the other side of the tower and evacuated its Mothership there. The Foreman had access to all of the Scrin's most advanced technology, including Rift Generators and Planetary Assault Carriers.

Aftermath
GDI went back there again but the tower is now indestructible.
