Metal Gear Solid: Guns of the Patriots is written by Project Itoh.

Solid Snake is a soldier and part of a worldwide nanotechnology network known as the Sons of the Patriots. Time is running out for Snake, however, as he will soon succumb to the FOXDIE virus, but not before spreading the disease to nearly everyone he encounters - in essence becoming a walking biological weapon.

Snake will need every advantage he can get, as the SOP network is about to be hacked by his old enemy Liquid Ocelot, and whoever controls SOP controls the world.
