Global sell-in numbers for Dead Island have now reached 3 million units since launch.

Publisher Deep Silver previously announced the game shipped 2 million copies worldwide to retailers in its launch month this past September. They did not provide a sell-through number, however.

"Dead Island has sold very, very well over the holiday season and we are thrilled that it has sustained a robust level of sell-through since launch in September," Aubrey Norris, Manager of Marketing & PR for Deep Silver told Game Informer.
