Awesome mod, read the first page, didn't see anyone explain Tiberium, so here I go:
Quote:
Tiberium is of course an alien semi-organic mineral. It was designed to leach valuable metals out of the ground(Iron, gold, platinum, some carbon here and there, etc) Due to its highly reactive nature, it's also a great energy source. Tiberium can be refined by heating and separating out the metals it forms into its alloy. Tiberium waste is then disposed of, or repurposed in weaponry.
After years of environmental damage and proliferation of Tiberium, GDI discovered that sonic projectors(like super-focussed speakers) set at the resonant frequency of tiberium would destabilize the crystalline matrix, essentially breaking it apart at the atomic level and rendering it unable to regrow. This development led to GDI's reclamation project and the maintainability, or in some cases creation, of Blue Zones.
Later, the Scrin came into play, having been duped into thinking the planet was ready for harvest, when in fact it was far from it as the Human race still lived.
They use tiberium as an all in one construction material, weapon, fuel, and healing salve.
As for the mod, I think the green tiberium could use a nice glow effect, but nothing too heavy as that could lag. I can't tell the green apart from plants in that screen shot.
For actor immunity, I suggest scripting an item, call it sonic emitter, it causes the actor's armor to resonate at tiberium's frequency. Either that, or of course make mutants/hazard suit infantry.
Something that might be worthwhile: Make the crystals harvestable, but work like Gold used to where an actor has to pick up bricks and deposit them, but instead of putting them in a rocket, they need to drop it in a refinery. This would make harvesters viable while adding some growth control.
Edit:
Read that Commodore no longer plans on working on this, but my post still stands, if anyone wants to, I think they should do that^.
