Multiple users have reported running into disc read errors while attempting to play the Xbox 360 version of Modern Warfare 3. In a forum thread on Xbox.com that spans 14 pages, a number of gamers have complained of consoles either failing to recognise and boot up the title, or an "unable to read from disk" message popping up at various stages during gameplay.Some of them have continued to encounter the same problem when trying their copies of the game on multiple systems, suggesting the issue lies with individual discs rather than consoles.
"If the game doesn't work on multiple consoles, it points to an issue with the disc, and I'd recommend you replace it," was one piece of advice offered by Microsoft support staff.
Individual users have also reported experiencing the disc read error with multiple copies of the game tried on a single console.
