Sony and Konami have partnered on a new Metal Gear Solid: Peace Walker MP3 player, no doubt modeled closely after the kind of MP3 players used by real mercenaries in 1974. The NWD-W253Z Walkman is a special edition of a new waterproof (!), wrap-around Walkman MP3 player, featuring an original camouflage design and preloaded with six songs from Peace Walker.

The 4GB Walkman will be released in Japan in "mid-May" for ¥11,800 ($128). Each order will include a voucher for downloadable in-game characters (in Walkman apparel, of course!). One version of the device, limited to 2GB, will become available in the US at an unspecified date.
