Food is not the only thing that Metal Gear Solid creator Hideo Kojima tweets "“ although he does spam a lot of it, the man eats a lot "“ he recently tweeted about the Fox Engine's facial system in the form of pictures.
According to Kojima, most of it is simply placeholder data and the shaders are temporary as they are still testing. It's certainly not Snake Eater's Volgin, he assured fans, just an expendable, nameless character.
Details on the new Fox Engine are still rather scarce. We do know that it's a multiplatform engine that supports development for all major systems including PS3, Xbox 360 and PC.
