Tiberian Apocalypse is a Partial Conversion for Command and Conquer 3: Tiberium Wars with the goal to create a true Tiberian Sun sequel. GDI, Nod and the Scrin are getting a complete overhaul.
The year is 2050, Earth is largely uninhabitable and split in three kinds of zones: Green Zones, here Tiberium contamination is relatively low, few to no Ion Storms, most of these are at the Polar, and other very cold, regions, Yellow Zones, where Tiberium contamination is moderate, and Ion storms are frequent, most of these are desert, yet house more than half of Earth's total population. And finally, Red Zones. These no longer look like Earth. Tiberium everywhere, unbreathable air, constant Ion storms, near the borders between Yellow and Red zones, winds can rise to speeds that can tear the flesh right of a human's bones. Recently, Red Zones have started to grow dramatically, and so far nobody has been able to understand why. Samples of Tiberium from the growth areas gave no clue as to how or why this rapid expansion happens, but one thing is for certain: If it isn't stopped quickly, soon the entire planet will be uninhabitable.
GDI Took to the skies, mostly. They operate from huge command-ships, the legacy of the Kodiak, and from the Philadelphia. At the beginning of the Third Tiberium War, that was about 5 years ago, Nod tried to destroy the Philadelphia, by taking offline one of the ASAT hubs, and then attempting to nuke the Station, the system was returned to service just in time to intercept the missile. Since then, 5 more stations similar to the Philadelphia, have been constructed.
Nod is operating from the Temple of Nod in Sarajevo, and several Montauk-like vehicles. Their tactics haven't changed much since the second Tiberium War, relatively cheap and fast vehicles in elevated numbers at first, later then equipment that doesn't look like from this World. As opposed to what many assumed, Nod did not move away from Cyborgs, to the contrary, it is now frequent that even basic infantry may have a cybernetic eye, or artificial muscles and bones in some parts of the body.
Not much is known about the Scrin other from what was learned from the Tacitus: They are a species dependent on Tiberium for survival. They first seed Tiberium on a Planet, expecting it to eradicate all civilization on the planet and transform it into a ball covered in the green crystal which would then be reaped by their Harvesting fleets. When they first arrive on a Planet ,they build large portals, these have the aspect of three intertwined towers, with a bright light shining from the center. Lately, more and more people claim to have seen UFOs and otherworldly 'beings' near the borders of red Zones, but none of these have been confirmed so far.
GDI: Slow moving steamroller with many guns.
Nod: And suddenly...NINJAS!
Scrin: Shoot that man! And some more please. Almost there, shoot him some more. Wha-? He is already dead? Oh well.
