The Borderlands franchise has seen a big bump in the last few months in the lead-in to Borderlands 3's launch in September, with Borderlands 2 reaching 22 million units.
That's up from 20 million units back in May. In total, the entire franchise has sold 48 million units, up from somewhere over 43 million units again reported back in May.
"I think [the sales boost] is a reflection of the fact that the Borderlands IP is stronger than ever, even though it's been eight years since the last release," said Take-Two CEO Strauss Zelnick to GamesIndustry.biz. "I think there's a whole new generation of consumers who are super excited about Borderlands. That bodes well as we head into the September release. We'll see how it does, but we feel really good."
As of 2018, the PC version accounted for 11 million copies.
