Development Gag: The fact that Shelly "Bombshell" Harrison is stated to hate bubblegum and sunglasses gains additional meaning if you know that the game was originally supposed to star Duke Nukem, who is associated with both those things.
Divorced Installment: The game was originally conceived as Duke Nukem: Mass Destruction, but a legal dispute arose over use of the Duke Nukem intellectual property. (Specifically, Gearbox Software said that their deal with Apogee Software - the one which resulted in Duke Nukem Forever finally coming out - precluded Apogee from publishing any more Duke Nukem games.) As such, Duke was replaced by Shelly as as the game's protagonist.
