A Helping Hand

Downtown Sydney is a Nod mission in the Third Tiberium War to help GDI forces in Sydney to defeat the visitors in just ten minutes, evacuate GDI military commanders, who are in charge of the base in the city and civilians to safety until Kane, Nod's leader, abolished the alliance by putting a nuke from Nod's base on GDI.

Background
After a massive battle increased at the Sydney City Wall by Nod destroying alien technology and capturing the GDI lab behind the wall, Kane sent his commander who is the veteran of the Nod campaign against GDI and now, the visitors to Sydney where GDI fought helplessly against the Scrin to form an alliance with Nod until the ten minute part is done.

The Battle
At Nod's base of operations, the commander is forced to help GDI for ten minutes and the evacuations had began which GDI sent V-35 Ox transports, carrying civilians and GDI military commanders to safety but the Nod commander stayed there without aid. A Nod Saboteur captured the only tech building, a Tiberium Spike from the southern part of the GDI base.

Aliens attacking GDI
While Nod forces stood there, hopelessly to help GDI, the aliens brought in an arsenal of infantry, vehicles and aircraft to the front door of the GDI base.

GDI forces tried to push them back but the Scrin repelled them and also destroyed one GDI Airfield or maybe, two for the most of it. The Nod Commander built an Air Tower, some defenses, a Secret Shrine and a Tiberium Chemical Facility to destroy GDI and defend their own base.

As the time was nearly up, Kane resurfaced and told the Nod Commander that someone else in the Nod faction was responsible for the alliance. He told the commander to nuke the base with a Nuclear Missile, if the Nod Commander wishes to and he did.

Destroy GDI
As the aliens are trying to storm the base, GDI's Construction Yard was hit with a Nuclear Missile which came from the Temple of Nod, the superweapon for the Brotherhood and while this was an unfriendly way for GDI's disgrace, the Nod Commander sent more weapons at GDI, destroying it to rubble for the set-up of their Ion Cannons in the outback and as all of GDI was destroyed, Nod celebrated a massive victory to destroy GDI's alliance.

Aftermath
The Nod leader, Kane was happy with his Commander who destroyed GDI on his orders and gained control of the Brotherhood of Nod faction. The alliance was totally destroyed and Nod was sent to Ayers Rock to avenge on their second in command, General Qatar who was behind the GDI-Nod alliance in the Sydney City Wall mission.
