Borderlands 2 ships over five million units worldwide

Borderlands 2, the sequel to 2009's co-op first-person shooter/looter with more guns, more mayhem, and more wub wub, has become one of the "most popular video games of the year", according to an announcement from 2K Games and Gearbox Software.

The publisher revealed that more than five million units of Borderlands 2 have been sold-in to retailers worldwide. With the release of the all-new Mechromancer character class, the Captain Scarlett and her Pirate's Booty add-on campaign, and three additional new add-ons scheduled to release throughout the coming months, Borderlands 2's will only continue to gain momentum.

“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.”

Gaige, the Mechromancer, was released earlier this month for free to those who pre-ordered the game from participating retailers. For those who are not members of the Premiere Club, you can get the fifth playable class separately for $9.99 (800 Microsoft Points). Captain Scarlett and her Pirate's Booty, the first add-on campaign content for Borderlands 2, was also released earlier this month and can be downloaded for free by anyone who has purchased a Season Pass. It can be bought separately for $9.99 (800 Microsoft Points).

“The overwhelmingly positive response to Borderlands 2 from our fans has been incredible,” said Randy Pitchford, President of Gearbox Software. “Players have embraced Borderlands 2 as their next hobby with over 50 million interactions with Claptrap in the central town of Sanctuary and 12,000 real world years’ worth of time spent shooting and looting their way through Pandora!"
