Battlefield 3 has sold 5 million copies in its first week since release, according to publisher Electronic Arts’ internal numbers. The sales make it EA’s biggest-selling game ever.

“From Tokyo to Los Angeles, Sydney to London, millions of fans have been playing all weekend long - we are overwhelmed by the global response to Battlefield 3,” said EA’s Patrick Soderlund.

EA added that, in spite of intermittent server difficulties, service uptime had stabilised at 98.9 per cent.

“It is extremely gratifying to deliver an entertainment experience that delights our fans, and to have the opportunity to introduce new people to the franchise. Already, we are seeing unprecedented play times and online activity which is very rewarding. This launch solidifies Battlefield as a leading entertainment brand.”
