Among the many things that Metal Gear series creator Hideo Kojima is known for - microblogging about everything he eats, for instance - we're particularly interested in his proclivity for breaking the fourth wall. The first Metal Gear Solid's controller port trick is but one example of his bizarre, outside-the-box thinking when it comes to making games. As it turns out, he was trying to do so as early as 1988, when he first worked on the original Snatcher for Konami.

During a roundtable interview session today, just ahead of his appearance at the Smithsonian's "The Art of Videogames" event, Kojima detailed his first forays beyond the game as presented on screen. "Back when I was making Snatcher, which is a PC game - at the time we used floppy disks," he said. "One thing that I wanted to do that I wasn't able to do was that I wanted to have a secret message on the disk -- actually have something written or printed on the disk." Kojima wanted the missive to be heat activated - which is to say "activated by the heat created by the disk drive itself." S ... seriously?

"So maybe when you put it in your disk drive and you're playing for about fifteen minutes, the heat from the disk drive interacts with that chemical and creates a certain smell. It smells like blood or something like that," he said through a translator. "And when you pull it out you see like a dying message on the disk. That was actually an idea I had for the original Snatcher but unfortunately I got yelled at for it and they didn't let me do it." Isn't it always "they?" Those guys are the worst!
