Borderlands 2 is the bestselling game on 2k Games' roster, its parent company Take-Two has announced.
Reporting on its results for the third quarter of fiscal year 2014, Take-Two announced that Borderlands 2 has sold 8.5 million units since its release in November 2012.
This includes sales of the game across PC, PS3 and Xbox 360, including both the original game and the 2013 Game of the Year edition, putting it ahead of stablemates including the BioShock and NBA 2k series.
Developed by Gearbox Software, Borderlands 2 has also been confirmed to be headed to PS Vita, though no further announcements have been made since Gamescom 2013. It was offered free to PlayStation Plus subscribers in December.
