Borderlands 3’s publisher 2K says the looter shooter sold over five million copies during its first five days on the market, making it the fastest-selling game in the company’s history.That works out at 50 percent more sales than Borderlands 2 during the same launch window – a game which went on to sell over 22 million units.

The high figures were achieved despite backlash from fans when it was announced the PC version of Borderlands 3 would be an Epic Games exclusive. A press release from 2K announcing the sales records draws attention to the store figures in particular, saying “Borderlands 3 delivered the highest pre-order sales figures to date for a 2K title, as well as broke pre-order records with the Epic Games Store. Initial sales of Borderlands 3 have exceeded the label’s expectations and, in particular, PC sales of the title through the Epic Games Store have been incredibly strong.”

Over 70 percent of Borderlands 3’s sales were digital, and the game has consistently pulled views over on Twitch. 2K says it’s generated more than 14 million hours of content on the streaming platform, which is more than half the viewership that Borderlands 2 generated over seven years.
