Supreme Master Ninja Overlord's free trip to Tokyo!

Ninja Gaiden is undeniably one of the finest titles bestowed upon the gaming community this year, with its delectably well-balanced gameplay and gorgeous graphics. As if playing Ninja Gaiden over and over again wasn’t sufficient reward in itself, Microsoft is organising an Xbox Live! Master Ninja Tournament to acknowledge the skilled dedication of Ninja devotees.

The competition builds on a fairly simple premise. Register your Xbox Live! gamertag here: http://www.xbox.com/en-GB/ninjagaiden/tournament.htm, and then slice gullets and kick faces until your karma score swells to the same size as your blistered thumbs. You have until the 2nd September to prove your worth.

For the ultimate master uber-ninja of ultra-honour, two tickets to the Tokyo Game Show await. Obviously, infinite respect and glory are also at stake. Apart from that, there’s also a few T-shirts and sweatbands knocking around for the runners up.

And a word of advice for the winner. Those girls are not chiropractors.
