Metal Gear Solid 4: Guns of the Patriots (commonly abbreviated to MGS4) is an upcoming stealth action video game in the popular Metal Gear series. Directed by Hideo Kojima, Shuyo Murata and Yoji Shinkawa, Guns of the Patriots is currently being developed by Kojima Productions exclusively for the PlayStation 3 video game console. The game is being designed around the motto, "No Place to Hide!" MGS4 will reportedly be the last Metal Gear game developed by Hideo Kojima, and the last game in the series starring Solid Snake. The game will be released worldwide on June 12, 2008.
Set in 2014, five years after the "Big Shell Incident" (the events of the Plant chapter from Metal Gear Solid 2), Metal Gear Solid 4 portrays a world where the restriction of military intervention on foreign soil has been eased, fueling the need for private military companies (PMCs) to fight proxy wars for business purposes. Nanotechnology has become prominent, both to enhance the capabilities and enforce the loyalty of mercenaries. The five largest of these PMCs are owned by a single mother company named Outer Haven, which is operated by Liquid Ocelot. Amassing an army whose manpower rivals that of the United States, Liquid prepares to launch an armed insurrection. With the world once again in crisis, a rapidly aging and disillusioned Solid Snake is deployed into the Middle East by Roy Campbell to terminate Liquid. Guns of the Patriots will take place in five locations throughout the world, including the Middle East, South America and Eastern Europe.
