Dead Island has shipped over one million copies to retail in North America in its "first few days of availability", according to publisher Deep Silver.
The firm also pointed out that the zombie survival game has grabbed the No.1 chart position "in many global markets including the UK and France as well as on Steam", and said it will have "sold two million units globally to retailers by the end of this week".
"We're thrilled at the retail reception Dead Island has achieved in its first few days," said Geoff Mulligan, chief operating officer at Deep Silver.
"The critical 'first week' of game sales has been an enormous sales success for Deep Silver. We're working quickly with our distribution partner in North America, Square Enix, to restock shelves as quickly as we can."
It's a great start for the game, especially seeing as plenty of controversy surrounded its launch. A PC Steam blunder saw a severely broken development version of the game go on sale before a secret line of code describing a 'feminist wh*re' skill for female character Purna was uncovered, sparking outrage despite the fact it never appeared in actual gameplay.
