Metal Gear Solid V consists of two games - a prologue game, Metal Gear Solid V: Ground Zeroes, and its sequel, Metal Gear Solid V: The Phantom Pain.
The prologue, Ground Zeroes, takes place in 1975, after the events of Metal Gear Solid: Peace Walker. Big Boss, the main character, is working for Militaires Sans Frontières, or MSF, under orders from Kazuhira Miller to infiltrate a base known as Camp Omega in order to recover two prisoners. The prisoners are Chico, a young solider, and Paz, a Cipher agent.
In the aftermath of the events in Ground Zeroes, Big Boss falls into a coma for nine years and upon awakening forms a new mercenary group, the Diamond Dogs, assuming the codename "Punished Snake". In search of the men responsible for MSF's destruction, he ventures to Afghanistan during the Soviet war, where he encounters former rival, Ocelot. While initially driven to exact revenge, he soon unearths a plot by the Cipher organization to develop a weapon with the potential to surpass even the Metal Gear system.
