Deep Silver has stated that the title reached this landmark within the “first few days of availability” after its release on the continent last Tuesday (6th September).
The company also pointed out that the game had topped the charts in “many global markets,” including the UK, France and on Steam – before making the prediction that they would reach two million sales by the end of this week.
Geoff Mulligan, chief operating officer at Deep Silver, expressed his delight at the game’s performance so far: “We’re thrilled at the retail reception Dead Island has achieved in its first few days.”
As well as impressive sales performances around the world, the zombie survival game has received critical acclaim from the majority of high profile critics.
Despite this success, the developer has already had to release a patch for the Xbox 360 to counter specific problems.
The update includes improvements to “matchmaking, AI, quest and escort fixes, visual glitch fixes and a ton more,” according to the game’s official Twitter page.
PS3 and PC updates are current being worked on and are expected to be released soon.
