The PSP has been around for five years, and if you can believe it, there's five Metal Gear Solid titles to match. The latest, Metal Gear Solid: Peace Walker, takes the multiplayer-driven approach that has made Monster Hunter so popular and swaps giant missile-toting supertanks for Capcom's giant fire-breathing beasts. Kevin Kelly spent hours leveling up Snake and pumping enemy soldiers full of tranquilizers. And he seems to have loved nearly every minute, as you might notice here:

"There are few PSP games that capture the essential console experience on handheld. Arguably, it’s been over two years since the last one -- God of War: Chains of Olympus. Metal Gear Solid: Peace Walker feels bigger than its platform, and it's hard to imagine that all this gameplay can fit on a tiny little UMD. Although the controls are stifled by the nature of the device and the emphasis on multiplayer hurts PSP owners who don’t have gaming partners or a hard-wired PS3, it’s not enough to suppress this level of enjoyment and content. Kojima Productions has clearly done something right. While Peace Walker isn’t always perfect, it’s easily the best Metal Gear Solid game -- if not one of the best games, period -- on PSP."

Once I got past the toughness of some of the boss fights, I've been a fan of Peace Walker since playing it last April. Want to see how much Kevin likes it? See for yourself in this Metal Gear Solid: Peace Walker review.
