Microsoft's dipping its toes in the old number-cracking viral marketing thing again, only this time it's a bit more official.

Over on the UK Xbox site here, there's a code-beating competition running to win tickets to the London-based Halo 3 premiere that takes places the night before the game's launch.

Frankly, it's a bit too late on Friday evening for us to bother trying to work out what the hell a bunch of stupid codes mean on some internet PR exercise, but if you've got some spare motivation feel free to give it a go.

The competition closes on September 14 and you have to be over 18 to enter, because Microsoft really doesn't want to have to play dad to a bunch of 13-year-olds on the eve of the most important event of Xbox 360's life.
