Dead Island has shipped three million copies globally since its launch in September 2011, publisher Deep Silver has confirmed.
The company previously revealed that the zombie mashing action-RPG had shipped two million copies during its launch month.
Dead Island received a mixed reception upon release; some reviewers praised the game for its visceral combat and co-op elements, while others criticised its dodgy presentation and numerous glitches/bugs.
Rumors of a sequel cropped up early last month when developed Techland registered the trademark ‘Dead World,’ leading many to believe a follow-up is in the works.
