Set six years after the events of Snake Eater, Metal Gear Solid: Portable Ops features Naked Snake once again as the main character. In this game, Naked Snake wears a new version of the sneaking suit he wore in Snake Eater dubbed the "Close Quarter Combat Enhancer", which serves as the uniform of the FOX unit. Although already awarded the title of Big Boss, he prefers to be addressed by his former codename, believing that he has yet to surpass The Boss as a warrior. Snake finds himself involved in an armed uprising caused by the FOX unit in the fictional San Hieronymo peninsula in Colombia and learns that he has been convicted for instigating the revolt. Hoping to clear up his name, Snake forms his own team of specialists by recruiting both old allies and defecting enemy soldiers to his cause. He faces not only the members of the FOX unit, but also the first built Metal Gear prototype known as the ICBMG. He defeats Gene and obtains the fund for "Army's Heaven", a precursor to Big Boss's own Outer Heaven.
