"Metal Gear Solid 4: Guns of the Patriots" deals with "sense", which is a person's understanding of the world that is lost when they die. It also encompasses how some things cannot be passed down to future generations and be misinterpreted as well as the artificially controlled (and globally shared) sense-data of the new era's nanotech-enhanced soldiers. With "Metal Gear Solid: Peace Walker" the plot deals with the true nature of 'peace', and the concept of conflict in human societies. "Metal Gear Solid V: The Phantom Pain" deals with the themes "race" and "revenge" and how the latter can make one lose his humanity. Following the initial Metal Gear, each game has been a deconstruction of action movies and video games, using tropes to invoke the themes and ideas especially those of spy movies - it examines what kind of mind and complete control of a situation would be needed to pull off the absurdly complex and convoluted plans that rely on events completely within the realm of chance yet comes off without a hitch. Furthermore, it examines what happens to a child soldier forced to take up a normal life through the characters Eli also known as Liquid Snake in "Metal Gear Solid V: The Phantom Pain" and Raiden was also known as Jack in "Metal Gear Solid 4: Guns of the Patriots".
