At E3 yesterday, Hideo Kojima showed up to announce a new Metal Gear Solid game, this time for the PSP. Metal Gear Solid: Peace Walker follows Big Boss about ten years after the events of Metal Gear 3: Snake Eater, during the mercenary operation that gives rise to Outer Heaven in Costa Rica.

It appears to have a play style more in line with previous titles in the series than Metal Gear - requiring more sneaky, neck-breaking action than Solid 4: Guns of the Patriots, in which you could choose to shoot everybody in the face if you weren’t into the whole stealth thing.

The game, written and produced by Kojima, also appears to feature multiple Snakes, four of them together on the same team, which is a little confusing. I mean, yeah, it’s hot – just imagine the four of them, doing naughty things to a bunch of terrorists... I just mean that since they look the same, it might be confusing as to which one is talking, since they’ll all probably have the same gravelly voice; or which one is the player’s character; and how did there get to be four of them?

Anyway, the game is set for 2010, giving you plenty of time to brush up on the deep, confusing, but satisfying, Metal Gear back-story, and work out your complicated feelings for Snake.
