Snake charmer
Metal Gear Solid 4: Guns of the Patriots has been publicised as the last chapter in Japanese video game developer Hideo Kojima's acclaimed stealth-action franchise, which made its debut about 20 years ago. The game, published by Konami exclusively for Sony's PlayStation 3 console, sends the series' principal character, Solid Snake, in what is supposed to be his final mission against old foe Liquid Ocelot.
Set in a war-torn world, the Metal Gear saga includes seven titles covering a five-decade chronology (1964-2014). There have also been supplemental and related games, but these were outside the main narrative.
This time the Special Forces agent takes on the latest version of the game's antagonist, a walking tank with nuclear-launch capabilities.
The series is credited with popularising the story-driven, stealth-action genre, in which a player's aim is to avoid detection and eliminate targets silently. In Metal Gear Solid 4, an older and wiser Solid Snake uses his stealth abilities, new reconnaissance tools and an OctoCamo suit that allows him to blend in with the environment and sneak deep inside enemy locations.
