Back in the second Tiberium war there was an artefact known as the Tacitus. The Tacitus was used to construct the Tiberium Sun (as far as GDI could tell). The CCS has intelligence that states that there is more than one Taciti. The Tacitan, Tacitus, Tacitek and the Tacitow. All of these have different attributes.
The Tacitus...
The Tacitus is for knowledge. The only one that Kane was interested in, as Kane was hungry for knowing all. Kane also had an ambition to be omnipotent, and the Tacitus is able to guide the user to eternal life. When the CCS knew of the Tacitus, they attempted to destabilize it by applying a magnetic field to it. This would render the Tacitus unusable and dangerous, they gave it to GDI.
The Tacitan...
The Tacitan was successfully destabilized to the point of its destruction. However upon its destruction most of the western US states took significant damage. The blast yield was that of a 400 MTn Nuke. So the CCS tried to find a new way to destroy The Taciti.
The Tacitow...
The Tacitow controls the mutant lifeforms. Taken by the Forgotten, this remains all that is left after the ascension of NOD. All of the Tiberium on Earth was linked to this artefact but is now free of its influence.
The Tacitek...
The Tacitek is the weather controlling artefact. Almost nothing is known about the Tacitek. Only that the CCS researched it a lot.
With the misplacement of the Tacitow the Tiberium lifeforms have gone crazy.
Any ideas on Tiberium lifeforms will be looked at.
It explains how CCS got the weather controlling technology.
Any ideas? Hmm... my only idea was this Tiberium worm. There could be some more spieces of visceroids (5 colores and 5 spieces).
how about very rare large monsters like the eradicator (with no weapons)
or some kind of human size tiberium eating bugs (like spiders)and they can crawl on walls.
and you can gain something when you kill them i dont know what maybe something new from the mod.
or even buzzers can be a tiberium lifeform.
Buzzers are flying fish that require a Modified atmosphere, this is why they are Scrin operated. Viscroids, Tiberium floaters and Tiberium fiends are just some of the creatures making a comeback.
Or maybe Tiberium giant tick? It drains humans blood and life essence. On back, tick has a cocoon which grows up after every kill and is more powerfull, fe. tick can only kill infrantry, but after 5-6 kills can attack light vehicles, after 10-12 kills can attack bigger tanks. After 15 kills can attack air or structures or has a special abilities.
Humans after drain become a mindless zombie. They have many palps. In small number they are weak, but many and with cooperation with Tiberium giant tick are very dangerous. They attack by claws, palps and sometimes gun. What do you think about it? ;)
Tiberium buzzers may appear as an infection to Tiberium fields, like potato blight (just an example). Doing damage to the harvesting unit that collects it. Adding corrosion damage that hurts even Scrin.
