The game was meant to have a more realistic atmosphere, compared to Perfect Dark and Zero. Joanna Dark would have appeared, but would have a different, less feminine personality, including behavior such as smoking and flirting. During development, the main character was changed to an unknown male character, who would fight alongside Joanna. Near the end of the project's life, the game's concept no longer had anything to do with Perfect Dark. The game was changed to a mech first-person shooter, but was canceled.
