The player-controlled protagonist Jack is forced to help Cohen with the creation of a macabre sculpture, built around pictures of Cohen's former proteges whom he kills and photographs on his behalf, before he grants passage through his domain Fort Frolic for the player character to complete his objectives. Sander Cohen makes a further appearance as a major character in Episode One of BioShock Infinite: Burial at Sea, a downloadable content story expansion for BioShock Infinite which sets up the events of BioShock. He is voiced by T. Ryder Smith for all appearances.
