To unlock the ''Journey Of Discovery'' achievement in Nobodies: After Death, you need to talk to the one of the guest on the dancer and use these answers in order: ''You're really feelin' this track'' and ''It's New Year's right? Sure, hit me''. You will discover a complete new world (lol) and fail miserably the mission (and unlock the achievement). This can only be done in Operation Midnight.
