Ahead of the PSP launch of Konami's Metal Gear Solid: Peace Walker next month, Sony has announced a limited edition, camouflage-tastic version of its all-in-one W252 Walkman.

The W252 is also water resistant, so that means it won't let you down if you're pounding the pavement in the rain, or you build up a bigger-than-usual sweat down at the gym.

The game tie-ins aren't simply restricted to a bit of camo-design though, it comes with six exclusive tracks from the Peace Walker soundtrack pre-loaded and there's game unlock codes within the packaging. During the game, there are collectable Walkmans including vintage editions like the first-ever cassette-base Walkman from 1979.

There's 2GB of space for all of your tunes and a full charge will give you 11 hours playback. If you're pushed for time, a 3-minute charge will give 90 minutes playback. Which is around 80 minutes more than our work-out usually lasts.
