Robert Bowling, community manager for Modern Warfare developers Infinity Ward, has returned to his Tweeting ways after a week's well-deserved silence.

And it's straight back to Call of Duty PR work, too, with the revelation that since its release late last year over 25 million people have played Modern Warfare 2 across the Xbox 360, PS3 and PC.

Those numbers are of course tracking only those who have played the game in some way online. Which would be the vast majority of gamers, but still, it means the actual number of people who have spent time with Modern Warfare 2 would be a little higher.
