Metal Gear Solid Delta: Snake Eater

During the height of the Cold War, CIA operative Naked Snake is sent into the Soviet jungle to extract defecting weapons scientist Sokolov. The mission collapses when his mentor, the legendary soldier known as The Boss, defects to the USSR and leaves him for dead. Weeks later, Snake returns under a new codename — Snake Eater — with orders to kill The Boss, finish the rescue, and destroy the Shagohod, a nuclear-armed walking tank that could shatter the balance of the entire Cold War.
