Isaac has a split personality in Dead Space 3 and "Shadow Isaac" taunts Isaac every chance he gets. For example, Shadow Isaac calls Isaac an idiot after he falls into a tunnel late in the game. Isaac complains this rescue mission isn’t his mission and the shadow retorts and tells Isaac he turns his back on the wrong things. Isaac shouts to the shadow to shut up, who replies to Isaac by saying he’s making all of the noise. Dead Space 3 is going to have this kind of banter – a sarcastic shadow and Isaac crossing tongues. Players will be able to see the shadow as a separate on screen character.
