Of alien origin (We first are hinted about then confirmed later on in the series), this crystal is an engineered material that uses whatever around itself it can to adapt to the environment and spread in the most efficient way; First assimilating into a vegetation-like state to ensure a speedy first stage of development where tree-like organisms spread noxious fumes which were very small 'seeds' which would proginate the crystal form, and later digging deep into the ground and spreading in a completely crytalline form underground thus manufacturing or 'growing' more of the material in a run-away effect. Could almost be considered a form of life with its organic ability to conform to any form of life and environment.
As this series is owned by ea, I know it would be hard to incorporate directly into the game, however a mod based on this idea would surely be a boon to this game and add a very dynamic effect to any map.
I don't know much about modding, which is why I came here to throw the idea around a bit. I'm sure I'm not only C&C fan from the older games that would have an absolute blast with this type of mod.
