It’s a truly brilliant way to keep the tension of the scene flowing, all while giving both players something interesting to do. It culminates (at least in the demo I played) in Leo fighting his way out of a corridor in a scene that directly references Oldboy’s famous single-shot fight.
By switching character, the game’s switching player too, each putting on a chase scene show for the other.
Here, the split-screen disappears entirely while a single shot follows Vincent and Leo in turn, the camera flying through air vents or down stairwells to keep up. The best scene I’ve played so far sees both lead characters escaping from a hospital.
