PC World writes: "At the outset of Metal Gear Solid 4, director Hideo Kojima can't help but respond to the aphorism that launched Tim Cain's legendary Fallout. "War...war never changes," growls Ron Perlman as the latter's ironic intro rolls. But in Metal Gear Solid 4, the opening line runs exactly the opposite: "War..." rasps Snake as he crouches in the back of a transport motoring onto a desiccated battlefield. "War...has changed."
Boy has it. In MGS4's dystopian rendition of our near-future, a cabal of synthetic intellects purveys war as a series of proxy battles to sustain a global algorithm that enhances battlefield predictability at the expense of free will. Humans are colonized by nano-machines and weapons are biometrically keyed to each soldier's DNA, relegating the ability to fire guns and launch rockets to remote-control overlords. Private military contractors or PMCs fight proxy wars without ideological liabilities and dictate the world economy. The world economy becomes a war economy, and war becomes pitilessly routine."
