The full game of Halo: Reach has reportedly been leaked online.
According to online news sources, the review code of the game was this week uploaded by Microsoft onto Xbox.com - with special access restrictions in place.
However, hackers managed to circumvent the block - and the title is now in the wild. It is unclear how widely the leaked code has been distributed, or if the hackers have made it publicly available - but spoilers have reportedly appeared on NeoGAF and other games sites.
Writing on Bungie fansite HBO, Louis Wu revealed: "Just a warning - looks like Reach is out there in the wild. This time it seems we can't blame the French; apparently, a group of modders figured out how to fool Xbox.com into allowing a download of the copies put up for some press... So if you're looking to play Reach unspoiled... now might be a good time to go dark."
Oh dear. This isn't the first time a Halo game has leaked early, either: Both Halo 2 and Halo 3 made their way onto the 'net before they hit shelves.
Halo: Reach is due for proper, above board release on September 14.
Bungie this week confirmed that series legend Master Chief would be in Reach - if only as a voice.
