Effects
Up close and personal, that's how you like it. Your sneak attack criticals with pistols, revolvers, and submachine guns, whether guns or energy weapons, all inflict an additional 20 percent damage.

Behind the Scenes

 * The Professional is a reference to the french movie Léon, also known as 'The Professional' and 'Léon: The Professional'. The plant next to the Vault Boy is a reference to the movie. Also, his clothes, hat, glasses, and face stubble portrayed by Vault Boy are identical to the character played by Jean Reno in the movie.

"The rifle is the first weapon you learn how to use, because it lets you keep your distance from the client. The closer you get to being a pro, the closer you can get to the client. The knife, for example, is the last thing you learn."
