Metal Gear Solid: Peace Walker for the PSP is a “true sequel” in the Metal Gear Solid franchise, and it’s going to offer some interesting features. Especially Co Op features. This IGN article talks about Co Op mode and Snake In mode. When two players are close to each other they can share a life gauge and weapons. If they get REAL close to each other one player controls both players movements, but the other player can still shoot. So combat becomes more important for the second player while stealth is the focus for the first player. Sounds crazy, but it’s Metal Gear, I’m not sure what you were expecting.
