Metal Gear Solid: Peace Walker takes the series in an exciting new direction with incredible visuals, as it sheds new light on well-known adversaries and allies, along with a wealth of new characters. In true METAL GEAR SOLID tradition, Metal Gear Sold: Peace Walker drops the player into a series of hostile scenarios, as a terrible plan for world domination is revealed. In addition to solo operations, players can team up via the game's multi-player CO-OPS (CO-operative OPerationS) mode. This extends to key gameplay advances, with players administering medical help to colleagues, sharing munitions, or providing cover for each other using the Snake formation to cover each other's blind spots.
