Okay, so technically the name of the cat you play as in Murdered: Soul Suspect (Airtight Games, 2014) isn’t Ronan O’Connor. I don’t know what the cat’s name is. Ronan O’Connor is the name of the man whose ghost you’re playing as, who can possess local cats at will. This is necessary, because cats can do cat parkour, which makes them more mobile than ghosts.
Yes, there is cat parkour in Murdered: Soul Suspect. There is also a dedicated “meow” button, which sadly Ronan doesn’t have when he’s in his human-shaped ghost form, for some reason. Video of some lithe Ronan-possessed cat parkour action below the fold.
