Onimusha & ICO on PlayStation

I presume you are referring to the Killzone tech demo? I've heard that footage of the oil rig stage was briefly featured in a making of documentary - along with the soundtrack plus some concept artwork - in the rare PAL version of the collector's edition (which is a lot harder to find than a certain other FPS I could think of with its supposedly "limited" tin release).

What's known about the early prototype of Killzone, which was known back then as Kin, is that Lost Boys were really pushing the PlayStation graphically and hunted down specifically by Sony to do the same for its next system. Of course, today Guerrilla has been signed exclusively to Sony and will hopefully be able to live up to its promise of getting its next game to look just as visually stunning as the E3 tech demo shown last year...

P.S. Does anybody here own the Killzone Collector's Edition, and can they confirm whether it really does have the "Kin" video or not as I'm quite interested in tracking down a copy of this version...
