The Global Defence Initiative fights to preserve the free world. We fight to rid our world of Tiberium a dangerous and hostile alien substance that threatens our very existence. Think of tomorrow Commander think of the world in ruin, imagine no children running around and playing, streets empty and houses abandoned, imagine a world in chaos and disarray. This is what's going to happen if Kane and his fanatically brotherhood succeeds, together we might just stand in their way to prevent this chaos from becoming complete.
