Metal Gear Solid V: Ground Zeroes serves as a prologue to Metal Gear Solid V: The Phantom Pain and takes place one year after the events of Metal Gear Solid: Peace Walker. Players take control of the legendary Snake (a.k.a. Big Boss) and infiltrate the Cuban facility Camp Omega, where Paz and Chico are being held as hostages. They possess crucial information that Snake and his confidant Kaz Miller desperately want to keep secret for the continuation of their private military organization. Ground Zeroes features a daring rescue mission, the unpredictable consequences of which set the stage for The Phantom Pain. It also introduces the highly anticipated open-world gameplay mechanics, making it the perfect bridge to earlier titles in the series.
