Borderlands 2 is on track to become the highest-selling title in 2K's history – as it nears 6m copies sold.
Speaking in yesterday's financials call, Take-Two CEO Strauss Zelnick revealed Gearbox's FPS sequel was the company's biggest earner in terms of digital sales across the past 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 Season Pass."
