Microsoft Halo 4 launch countdown continues as game leaks online
Master Chief makes premature ejection
Code for Microsoft's upcoming shooter Halo 4 has leaked online three weeks ahead of the game's launch, prompting investigation and action from team Xbox.
Images of Halo 4 game disks  appeared up on the NeoGaf forums last Friday and footage of the eagerly awaited FPS being played has since flooded the net.
Fans are warned to steer clear of any unofficial videos they find on YouTube so as not to spoil the game's narrative when it becomes officially available on 6 November.
Microsoft is apparently working closely with law and security agencies in the meantime to unearth the source of the leak and clamp down on those uploading confidential content to the web. It said the leak will not affect its launch plan.
It's certainly all about keeping rhythm at Redmond HQ right now. This week not only sees Microsoft launch a Spotify rival , but it is also touting a Halo-related competition for the budding music producer.
The Halo 4 Soundtrack Remix Contest  encourages entrants to choose from three original tracks from the game's score, download audio clips and get remixing for a chance to win various exclusive prizes. Check out the website for further details on how to enter. ®
