Gamespot got to look at a private trailer with Mike Verdu, and posted their impressions
. Here's a snip:
According to the trailer, the coverup didn't quite work out, thanks to the meddling of C&C's classic "bad guy" faction, the Brotherhood of Nod. Led by the evil mastermind Kane, Nod discovered tiberium's other potential as a powerful energy alternative, and attempted to discredit the GDI by exposing the coverup in the year 1995 (the year in which the original Command & Conquer game was released). This sequence of events polarized the world, so that the world's inhabitants aligned themselves with either GDI or Nod, a standoff that was threatening enough to global stabilty until, as the narrator of the trailer explained against a wide shot of Earth from outer space, "they came."
So it looks like the Scrin after all. Gonna be an interesting story they're aiming to tell. Full article here
