N.U.D.E.@ Natural Ultimate Digital Experiment

N.U.D.E.@ Natural Ultimate Digital Experiment is a life simulation video game developed by Microsoft Game Studios Japan and Red Entertainment, released exclusively for the Xbox in Japan by Microsoft Game Studios. In this simulation-style game, the player assumes the role of tester for a new product: a female humanoid robot called P.A.S.S. (Personal Assist Secretary System). The robot starts with minimal functionality and must be taught language and tasks by the player. This is achieved through voice commands issued using the included headset, the Xbox Communicator. The game incorporates the Xbox's internal clock to track time, which influences gameplay in various ways.
