During dialogue scenes, the player can generally choose between three different approaches: "suave", inspired by James Bond from Dr. No (1962) and sequels; "professional", inspired by Jason Bourne from The Bourne Identity (2002) and sequels; "aggressive", inspired by Jack Bauer from 24 (2001).
Alpha Protocol has a lot of similarities with the Bourne movies. Both Mike and Jason are being hunted by their former agency and they both want to take revenge on their former agency. Also, the "Professional" dialogue option is based on Jason Bourne's personality.
In the game, Alpha Protocols motto is "quo nemo sequi potest". In English, this means 'Which no one can follow'
