The British Board of Film Classification has stamped Modern Warfare 2 with an 18 rating in the UK.
Infinity Ward's sequel passed without any cuts, and will be the first of the Call of Duty series to carry an 18 certificate.
Interestingly, the BBFC listing makes no mention of Call of Duty, which means Modern Warfare 2 will be the title. Finally.
Will an 18 rating impact the potentially record breaking sales potential? It didn't slow current launch day/week record holder Grand Theft Auto IV.
Incidentally, the BBFC still has UK power until PEGI is declared the UK standard by law. That will likely not be this year.
