Entering the service of Allistair Tenpenny within the last twenty years, Mister Burke has made his life considerably easier.
Following Tenpenny complaining about the sight of Megaton on the horizon, Mister Burke offered to handle the situation. Burke intends to recruit an assistant to detonate the undetonated atomic bomb at the center of town. He has approached Andy Stahl about his plan, promising to move his restaurant, The Brass Lantern, to a safer area if he assists him.[Pub 1]
He can be seduced by a female Lone Wanderer with the Black Widow perk, and can be asked for 500 caps or to spare Megaton. If asked to spare Megaton, he will disappear from the game, but will leave four love letters for the Lone Wanderer with Colin Moriarty.
Refusing his offer, or disarming the bomb without speaking to him, results in a possible encounter with several hostile hitmen during a random encounter.
Accepting his offer and reporting him to Lucas Simms results in Simms getting shot and killed while trying to arrest Burke.
He will become Roy Phillips' right-hand man, if the ghouls take over Tenpenny Tower before meeting Burke at Megaton.
He has a house in Megaton, but has no key for it. Stealing items from it does not result in Karma loss.
He is one of only nine named characters in the base game to have "Very Evil" Karma.
He will panic and not fight back, if one tries to kill him on the Tenpenny Tower balcony.
Mr. Burke's script was written by Emil Pagliarulo with the voice of Wes Johnson in mind. Johnson ended up voicing the character by taking the sinister undertones from his performance as Lucien Lachance in The Elder Scrolls IV: Oblivion, but subtracting Lucien's accent and adding a more "corporate" tone.[Dev 1]
Mister Burke does not exist in the Japanese version of Fallout 3, thus disabling the "detonate the bomb" option in The Power of the Atom as the Lone Wanderer cannot get the fusion pulse charge under any circumstances.[Ext 1]
He, alongside other characters involved in his path of the quest, have Japanese voicelines that never go used.[Ext 2]
Playstation 3 If the Lone Wanderer kills Burke, after a long while he may respawn, and can be found standing beside the bomb if it is disarmed, though he cannot be engaged in conversation. [verified]
PCPlaystation 3Xbox 360 If the Lone Wanderer kills Burke and disarms the bomb, they will still encounter hitmen. If their bodies are looted, they will have contracts instructing them, signed "-B", as if the Lone Wanderer had not already killed Burke. [verified]
PC If Lucas Simms is told about Burke and one pickpockets Burke's ammo before Simms confronts him, Burke may enter into his draw sidearm animation and loop indefinitely. Simms may still drop dead however, as if Burke had killed him, possibly after leaving the saloon. [verified]
↑Lone Wanderer: "Have you ever heard of a Mister Crowley?" Burke: "Never heard of him. Wait. I think I do remember Allistair Tenpenny mentioning him once. Something about a job. It was before I met him." (Mr. Burke's dialogue)
↑Lone Wanderer: "I've been wondering... why blow up Megaton?" Tenpenny: "I complained off hand one day about how I thought that heap of metal on the horizon was a bit of an eyesore. Mister Burke offered to take care of it." (Allistair Tenpenny's dialogue)
↑Lone Wanderer: "Wait... You're going to destroy the town?" Burke: "No, no, I'm merely a recruiter. YOU get to have the real fun. The undetonated atomic bomb for which this town is named is still very much alive. All it needs is a little motivation. I have in my possession a Fusion Pulse Charge. Once rigged to the bomb, it will be detonated, by you, at a secure location. Easy money, my friend." (Mr. Burke's dialogue)
↑"Andy, 23, seems to be very quiet and reserved, which serves his role as the business manager of the restaurant. He is actually extremely crafty and manipulative. Unbeknownst to his brother and sister, Andy has been talking to Mister Burke about his insidious plan to blow up Megaton so he can move the restaurant to a better, safer, more lucrative location."

↑"In the game you make voiceovers for two different characters. How did you prepare both of them, and made sure they would be recognized as completely different personas?" Wes Johnson: "I actually play a few robots as well as Fawkes and Mr Burke. Mr Burke was the easiest of them all to do, because Emil had written him with me in mind after our work together on Oblivion. He wanted someone who was basically Lucien Lachance’s Dark Brother from another Mother. So I used the sinister, unctuous tones of Lucien, made them more corporate and stripped the very slight accent off of him. They are slightly different voices, but they are enough alike that you will recognize it immediately. Especially Burke’s very first line, which was very Lucien. But beyond that, I just felt that Burke was unctuous, condescending, and really felt he was slumming every time he opened his mouth to your character. He doesn’t feel that he is evil himself. He just feels that he’s a businessman, and that he is in a completely different class than the scum he finds himself dealing with. I am not surprised in the least that people want to kill him after speaking with him. He’s a bit of a douche." (Wes Johnson; Planet Fallout Interview)
