Metal Gear Solid: Peace Walker review

Metal Gear Solid: Peace Walker has the deepest systems of any action game on the PSP, but its used price keeps it in eighth place. Konami's current store page sets the story ten years after Metal Gear Solid 3: Big Boss runs an independent military unit and is asked to investigate an armed group in Costa Rica, a country without a military. Missions mix solo infiltration with co-op alongside comrades, called SENYU, and competitive multiplayer. Between missions you grow Mother Base, an offshore facility with staff quarters, development labs and storage for captured weapons, which adds a management layer to the stealth. Konami's page describes the HD Collection version sold as the Master Collection Version, which supports online play for up to six and includes a Screenplay Book and Master Book. A used PSP UMD lists at $78.99 before sales at DKOldies, so players who only want to play may prefer the Steam release.
