Batman: Arkham City's worldwide sales
Ships 4.6 million units in a week.
Batman: Arkham City has shipped more than 4.6 million units worldwide in one week, Warner Bros. has announced.
The "week one sales figure" (shipped, surely?) is apparently double that of previous game, Batman: Arkham Asylum.
Batman: Arkham City was released for PS3 and Xbox 360 on 18th October in the US, and 21st October in Europe.
The PC version will arrive on 18th November.
Predictably, given the numbers above, Batman: Arkham City romped to the top of the UK video games chart yesterday.
