Metal Gear Solid: Peace Walker

Metal Gear Solid: Peace Walker is an upcoming game in the Metal Gear series to be released for the PSP in 2010, with Big Boss being the main character. The game was officially announced at Sony's E3 press conference on June 2, 2009.

The game will be set in 1974, ten years after the events of Snake Eater, four years after Portable Ops, and just two years after the Les Enfants Terribles project. The setting is Costa Rica and depicts the rise of Outer Heaven.

Plot Summary
The following is from the official Kojima Productions website:


 * Stories tell of a legendary soldier who, with Metal Gear in his command, had once raged war against the world. His name was Naked Snake, a.k.a. Big Boss. Now, in response to a world hungry for answers, the truth behind this legend will finally be told. The era is the 1970's. Big Boss had stationed his "Soldiers Without Borders" in Colombia, South America, where he was approached by a visitor from Costa Rica, "a Nation without a Military." In the wake of the Cuban Missile 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 "Soldiers Without Borders" move into action. In time, they would come to be known as the founders of "Outer Heaven."

Development
Hideo Kojima announced the game at Sony's E3 2009 conference, stating that the team that made Metal Gear Solid 4: Guns of the Patriots will return to help develop Peace Walker. Kojima is writing, producing and directing the game, stating that the game is not a spin-off, nor is it a side-story like Rising. Kojima refers to Peace Walker as the true sequel to the Metal Gear Solid franchise, while specifically calling Peace Walker "the MGS5 inside me." A trailer for the game shown at E3 2009 also described it as the "missing link" in the Metal Gear series. The same trailer also revealed multiple Big Bosses, possibly indicating multiplayer or co-op gameplay.
