METAL GEAR SOLID V: GROUND ZEROES takes place in 1975 and sets in motion a series of events that culminate in the stunning plotlines of METAL GEAR SOLID V: THE PHANTOM PAIN. GROUND ZEROES centers on Big Boss - legendary hero and mercenary - as he infiltrates a sprawling secret prison base called 'Camp Omega' in Cuba on a rescue mission. He soon finds himself alone behind enemy lines with a truly non-linear mission that showcases key advances to the series made possible by its use of the FOX Engine.

Continuing the story of Big Boss, METAL GEAR SOLID V: THE PHANTOM PAIN is the series' largest and most ambitious edition to date, expanding upon themes and content seen in its predecessor: METAL GEAR SOLID V: GROUND ZEROES. Set within huge open-world environments, METAL GEAR SOLID V: THE PHANTOM PAIN is brought to vivid life with realistic weather patterns and day/night cycles. Thus, players can adapt their tactics to match the changing environment, creating an intuitive and non-linear gameplay experience. Similarly, a host of acclaimed METAL GEAR SOLID features return in hugely advanced forms, including expanded CQC (Close-Quarter Combat) skills, vastly improved enemy AI, online elements that complement the single player campaign, and an all-new version of METAL GEAR ONLINE, a competitive multiplayer mode, included within the main game, that is currently live, online and available for users to play.
