The Metal Gear Solid: Peace Walker, the Konami-published stealth action game, will not hit the market until June 8, Sony proclaimed today.

Whosoever buys that bundle, he or she can avail a pair of unlockable in-game features in the shape of a Fox-branded camouflage uniform and the feature of stealth gun.

The customers can also avail the PSP package on the very day of its arrival in the market, shared Sony. It will include a standard version of the PSP in "spirited green”, 2 GB memory stick, a UMD copy of Peace Walker, a voucher for a downloadable movie yet to be announced.

It is a sequel to Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Portable Ops. It puts players in the role of Naked Snake or Big Boss once again and makes them look at the earliest stages of his Outer Heaven mercenary group. It is a full scale sequel in the Metal Gear series and not a side project, revealed its creators, Hideo Kojima and Konami.

This series of Peace Walker has cooperative multiplayer action for up to four players.
