Swery 65 was a pretty niche developer until Deadly Premonition hit it big. Well, big enough to become a game with quite the cult status. Although it was not the first game he ever crafted, it was the one which was a hit with Western players.
Many have been clamoring for a Deadly Premonition sequel. Unfortunately, that was not announced, but we did get a teaser trailer for the game D4. Very little is known about it right now since we just have a teaser to go off of.
Swery made the adorable tweet after the reveal of simply saying "D4 it's mine". We'll likely see a bit more of D4 on the show floor. The game is going to be an episodic exclusive on Xbox One.
