We can't get enough of custom XMB themes right now. Ever since the release of the RCO Icon Editor which has made it so much easier to create custom XMB's, just about every PSP developer on the planet has had a go at customizing their PSP, and giving you the option to install their themes yourself. This theme comes from wraithalchemist, and if you haven't guessed yet it's a theme based on the Xbox 360 game Gears of War.

Wraithalchemist doesn't want to take credit for what he hasn't done, as the icons included in this theme come from innercy and squid_lord, with wraithalchemist re-coloring the icons with a red tint to make them resemble Gears of War. I must say, as a bit of a Gears of War fan this theme fits in quite well with the game. Enjoy!
