Halo 4

Hey, have you heard of this Halo thing? It’s a series of games for the Xbox 360, and it seems to be popular.

How popular? In announcing the Halo 4 Infinity Challenge today—which you can read about here if you haven’t already—the company also revealed that the Halo franchise has now officially sold more than 50 million copies since the days of the original Halo back on the Xbox. As well, Halo fans have put more than 5 billion hours of playtime over Xbox Live into the series at this point.

So, sorry Master Chief—looks like your retirement from having to save the universe won’t be coming anytime soon.
