There have been several reports of Halo 3: ODST having disc reading error which have been floating on the internet. Microsoft have finally woke up and responded to the Halo drama.
A Microsot Rep said: “We are aware of a very small number of people who are reporting they can’t play the game. We are looking into it, but at this point it doesn’t appear to be a widespread issue.”
Halo 3: ODST disc reading errors mostly occur on the single player campaign and some of the reports say that the 360 itself crashes. Lets hope Bungie and Microsoft resolve this issue ASAP!
