The listing for Borderlands 3 on Microsoft’s store page claims that the game will support cross-platform co-op.
So far in the game’s short-but-loud marketing campaign, developer Gearbox has yet to say anything about cross-platform play. And yet here it is, in black and white, under the ‘Capabilities’ section of the Microsoft store listing.
We’ve reached out to Gearbox for comment. Hopefully it refers to full cross-platform compatibility, but chances are it more likely refers to co-op play between PC and Xbox One. A recent example of this kind of co-op is Sea of Thieves, although it should be noted that Rare’s pirate sandbox is a Microsoft exclusive, and thus would naturally be limited to Microsoft platforms. Still, there’s significantly less corporate mess to untangle with PC to Xbox cross-platform play than there is when Sony is involved.
