Cadaver747: It's from Freespace space "sim" game.
Yes, that's right, from the cutscenes about the ancients who had been destroyed by the Shivans millennia ago. Your turn!
Cadaver747: Oh yes, you are quite right! It's your turn now!
GameRager: Technically it's a bit wrong.....it was in the first game, in the NOD campaign......he is mostly right, though.
Tiberian dawn is the first game.
I was wrong about its place in the campaign though, Seth says it when he first introduces himself to you, had mixed that up in my memory with his death which was one of the most memorable scenes in the game.
