The minor scratches appear to be aesthetic, however. All affected discs reportedly play as intended when inserted into an Xbox 360. Still, it's impossible to tell at present if scratches will become a problem moving forward.
Microsoft CEO Steve Ballmer promised in July that his company would be "world-class when we do hardware" after it was revealed that an abnormal number of Xbox 360 units fail. A month later, Microsoft sent Halo 3 to manufacturing.
While the issue may seem expendable, prospective Halo 3 buyers must pay $70-$130 before taxes for the added game content. Standard game discs, which are housed in traditional casing, retail for $60.
Microsoft was not immediately available for comment.
