As part of its second-quarter financial results issued today, Take-Two revealed that Gearbox's Borderlands 2 has shipped over 7.5 million copies to retailers.

"Borderlands 2 has sold-in over 7.5 million units and counting, and is on track to becoming the highest-selling title in 2K's history," Take-Two president Karl Slatoff said.

Retailers had stocked over 6 million units of Borderlands 2 as of February, with sales spurred by the frequent release of downloadable content and the recent launch of a DLC-bundled Game of the Year Edition.
