Counting both retail and digitally distributed copies of Dead Island, total sales for the weird zombie action-RPG have surpassed five million units globally, Deep Silver announced today. In meaningless, arbitrary statistics, that shakes down to about 402.18 units sold an hour since the game was originally released in back in September of 2011.

By December 2011, Dead Island had shipped 3 million units worldwide, with a fourth million added to that total after another eight months. Today's figure, however, is our first look at how the game has actually sold, since shipped figures count all units sent to retailers, while sell-through/net sales only count what is actually purchased by a consumer. We're sure those Steam sales didn't hurt anything.
