Stories tell of a legendary solider who once waged war against the world. His name was Naked Snake, a.k.a. Big Boss, and the truth behind this legend will finally be told. The era is the 1970ï¿½s . Big Boss had stationed his ï¿½Soldiers Without Bordersï¿½ in Colombia, South America, where he was approached by a visitor from Costa Rica, a ï¿½nation without a militaryï¿½. In the wake of the Cuban Missle Crisis, as Latin America became a key to maintaining the power balance between East and West, Costa Rica had miraculously managed to maintain its peace and neutrality. However, in various regions of the country, a mysterious armed force seemed to be engaging in suspicious activities. Now, to preserve peace in this nation without a military, the ï¿½Soldiers Without Bordersï¿½ move into action. In time, they would be known as the founders of ï¿½Outer Heavenï¿½. Forge a new path and live the legend with Metal Gear Solid Peacewalker, the first official Hideo Kojima game on the PSP system.
