But it hasn't always been. Back in 1999, Guerrilla Games created a concept video for their first meeting with Sony. The video, which Hulst believes showed off the studio's "technical competence" practically has nothing to do with the Killzone we know now; but it marked the first steps towards a franchise which would go on to secure PlayStation legend status with the release of Killzone 2.
It's an interesting snap-shot in time. We wish more developers would release their concept videos. The ones in Uncharted 2 are amazing too.
