The Windows release of Borderlands 3 was exclusive to the Epic Games Store for six months, with the Steam release in March 2020. Documents unveiled during the Epic Games v. Apple trial revealed that Epic had paid to 2K for this exclusivity. Fan dissatisfaction with this exclusivity arrangement led to a review bombing of the Borderlands games on Steam. Valve, the operators of Steam, used their new processes to combat review bombing for the first time to suppress the negative reviews on the Borderlands games as a result.
