is sneaking up on the 6 million mark for units shipped, and well on the way to exploding 2K Games' sales records. Speaking in yesterday's financials call
, Take-Two CEO Strauss Zelnick said the rambunctious shooter was the company's biggest earner in terms of digital sales across the fiscal year.
"Building on its extraordinary launch in September, Borderlands 2
continues to expand its audience and remains on pace to become the highest-selling title in 2K's history," said Zelnick. "It has also been the largest contributor to our digitally delivered revenue this year, driven both by strong sales of full game downloads, and high attach rates for the title's add-on content, especially the Borderlands 2
The Gearbox-developed sequel had shipped over 5 million
back in October 2012. While shipments aren't the same as sales, it's worth noting the original Borderlands sold 4.5 million copies
as of August 2011.
