Microsoft Investigating Halo 4 Leak
We don't know yet if the full campaign of Halo 4 has leaked to the Internet. Microsoft still isn't commenting directly on reports that some users may have access to the game ahead of its November 6 launch.
Numerous Xbox Live profiles seen on several gaming forums have shown users playing Halo 4, though Microsoft isn't saying how severe the situation is. It's unclear if the Halo 4 content is from the final game or an unfinished build.
"We have seen the reports of 'Halo 4' content being propped on the Web and are working closely with our security teams and law enforcement to address the situation," a Microsoft spokesperson told Game Informer. When asked directly if the game has leaked, the spokesperson said they don’t have anything further to share at this time.
Various YouTube videos have also been reportedly removed that featured leaked content.
We'll update this story if any new information surfaces.
