In one of a series of videos released by Microsoft of developers offering their thoughts on Project Natal, Kenichiro Imaizmu, producer of the Metal Gear Solid series at Kojima Productions, revealed that Hideo Kojima had been leading the design of a custom controller for use with his "previous production," Metal Gear Solid 4. As Imaizumi described, the ideas were figuratively -- and literally -- shocking. "We tried running electric shock waves, install a pulse reader ... we also tried to build a controller that's receptive to the strength of the [player's] grip," he divulged. "We tried a lot, even a transforming controller." It's too bad none of these concepts ever saw the light of day; Kojima could have birthed a truly shocking DualShock.Imaizumi also extolled the virtues of Project Natal, mentioning its ability for gesture, voice and color-based interaction. But, as far as we know, Natal doesn't have the ability to zap players with electric shocks. (Though we've learned to never say "never" ... again -- see what we mean after the break.)
