The game originally started off a PlayStation 2 version of 007: The World is Not Enough, before making a new James Bond story and game altogether using the engine from said game. When asked about the game's delay and title change, developer Jon Horsley stated:
"We thought we could deliver a good [The World is Not Enough (TWINE)] game for the PS2--but we also thought we could combine forces with some of our other studios and deliver a great original Bond experience with Agent Under Fire. The extra time has provided us the opportunity to create an entirely new game, not tied to a specific movie, and address some points that we knew we couldn't get into TWINE under that timeline. And we cherish and respect our players too much to pass up the opportunity."
