The Journeyman Project 4 is the sequel to The Journeyman Project 3: Legacy of Time and continues the story where Legacy of Time left off. The player once again assumes the role of Gage Blackwood, and with the help of the artificial intelligence Arthur, struggles against an unknown enemy who "emerges from their past to once again threaten the future."[1]

Development on this title began immediately following the success of Legacy of Time and was scheduled for an October 2000 release date. The game's story and design were written and a working prototype was shown at E3 1998[2][3], but the project was shelved early in pre-production.
