The game’s floppy disk would have been coated in paint and then when it got hot it would ”release the smell” of the crime. Everyone shunned the idea.
Kojima-san reveals this was his idea during the planning stages of the original PC88 version of Snatcher. Everyone else opposed the crazy ‘game feature’ and so the Metal Gear creator now calls it the ”Dead Smell Project,” almost fondly.
Not only would the disk smelt of blood but it would have also revealed a message in the hot paint that said ”Search the house!” This was the exact message left by character Gibson as his dying message in Snatcher. How can they censor such genius?
Still Kojima-san has managed to sneak in a few game quirks that require something more from the player in the real world, like the fight with Metal Gear Solid boss Psycho Mantis which could be made much easier by plugging the controller into the 2nd slot.
