Before you pass out at the thought of any new Borderland title being a mobile, live service, Battle Royale game, I'm only joking: it's not true. In fact, no one knows what it's going to be. Still, what we do know is that it's called Mask of Mayhem (or has something to do with a Mask of Mayhem) and is set in the Borderlands universe. Other than that, you'll have to watch the Gearbox Panel tomorrow. Trailer below.
