Hideo Kojima has said that Metal Gear Solid protagonist Snake isn't as old as he looks in the series' latest installment, Metal Gear Solid: Ground Zeroes.
In the demo that showcased a fair amount of gameplay, it certainly appeared that Snake aged considerably. However, Kojima addressed the fan speculation surrounding Snake’s beard and grey hair by stressing it was a lighting effect that made him look old.
"Saw many tweet about Snake in grey hair after taking off the goggle. This is due to the rim-lighting."
Kojima had recently confirmed that Metal Gear Solid: Ground Zeroes is a prologue to Metal Gear Solid 5. The game itself is due for a release on the PlayStation 3 and Xbox 360 sometime during 2013.
