Worldwide sales for Horizon Zero Dawn exceeded 2.6 million units during its first two weeks of launch, Sony Interactive Entertainment announced.

The number includes both Blu-ray disc sell-through quantities and download version sales on the PlayStation Store.

The PlayStation 4 title was developed by Guerrilla Games and released worldwide starting February 28. It is the best-selling new first-party IP launch on PlayStation 4 to date and Guerrilla’s biggest ever debut.

Here’s a brief overview of the game, via Sony:

Horizon Zero Dawn is an exhilarating new action role playing game where you play as Aloy, a young hunter on a quest to discover her destiny among the remnants of the ancient past. The game is set in a lush, post-post-apocalyptic world where machines roam the land and mankind is no longer the dominant species.
