Starfleet Jedi

On one random Earth-sized planet colonized by a few billion humans, the sky darkens. Giant spores fly down, raining Tyranids on the unsuspecting populace, and begin attacking and devouring the native life-forms, absorbing and assimilating their DNA. The sky darkens again, as a MASSIVE Borg armada enters the system, and beams billions of Borg drones (standard, medical, engineering, and tactical) down to the surface, and they go after the planet's population and technologies. Now, here's where the twist comes in. All over the planet, there is a substance that has both beneficial and lethal properties. A substance called Tiberium.

Now, a three-way war between the Borg, the Tyranids, and the human colonists erupts. The humans have all the technology the Command & Conquer (Tiberium Series) humans do. How does this go?

I'm sad for your thread. Too complicated perhaps?
And is there much fluff about C&C aside from the games?

Besides, one would be invited to look into the topic of Borg nanoprobes vs those special immunization cells Tyranids have.

Aside from the manuals and the mediocre novelization of Tiberium Wars, no, not really.

Here's the info on Tiberium, though:

This would pretty much be a Borg versus Tyranids fight all the way, as the human colonists would likely wind up providing additional drones and or material for the Gene Stealers.

Tyberium would become a source of power, but I understand it's kinda toxic to biological life.
