D4 is a new mystery title from SWERY, Access Studios, and Microsoft Studios and it's apparently coming out tomorrow, September 19. The game is exclusive to the Xbox One.
This release really seems to have come out of nowhere, especially given how surprised most people on Twitter are reacting to the news of the release date.
