Xbox copies of Call of Duty: Black Ops were supposedly stolen yesterday, sparking fears that the closely-guarded title may be leaked online ahead of its release.

After several copies were allegedly snagged from the pressing plant in Alabama, attempts were made to flog them to interested parties through Xbox mod websites.

An image of one such disk with "Ungodly Leaker" written on it prompted speculation that Ungodly, credited with leaking Halo: Reach well prior to release, would repeat the feat with Black Ops.

True or not, developers Treyarch are said to have tried to buy the disks back, but since the company was said to be working a deal through a third-party, it's not clear whether that's actually the case.

Black Ops is tipped to be even bigger than its predecessor Modern Warfare 2, and Treyarch has released some mega trailers to wet our appetites ahead of it release on November 9. ®
