Horizon Zero Dawn has now sold an astonishing 7.6 million copies worldwide following its launch a year ago today. Sales at that level make the RPG from the creators of Killzone the "most successful new first-party franchise launch on PS4" to date, Sony said.

"We had huge ambition for Horizon Zero Dawn and as we approached the launch we knew people were excited, but to see sales of this volume is truly mind blowing," Guerrilla Games boss Hermen Hulst said in a statement.
