2K Games and Gearbox are today proud to announce that their sequel to their sci fi steampunk style open world FPS Borderlands 2 has sold over 5 million units to retailers since launching this September.

“We’re thrilled with the momentum of Borderlands 2 and it’s really a testament to all the hard work that the team at 2K and Gearbox put in to make this a must play game,” said Christoph Hartmann, president of 2K. “The Borderlands series has never been more popular, and with continued support through substantial add-on campaigns, Borderlands 2 has cemented itself as one of the industry’s mega franchises.”
