Mallet McBride is one of the vital escaped Tibbets prisoners. Like many of his escapee comrades, he carries one of the New Plaguemutations – a piece in a large and lethal puzzle that the Prisoner needs, and the same virus that inhabits the Prisoner's own body.
Mallet McBride is not a nice man. In fact, he's a downright asshole. If it weren't for the fact that Mallet was in prison for carrying Limit 115, he would be either in someone else's prison, or dead from a gunshot wound to the head. However, now that he escaped Tibbets Prison, he has chosen Hoover Dam as the place to sow his wild oats.
Mallet is a pretty big guy and a very skilled unarmed fighter. He's so good, in fact, that legend has it he once laid out a super mutant with one punch, though that legend has never been tested on Beatrice.
Mallet can be found in Dusty's Desires whittling the day away getting drunk and complaining. He takes the occasional job with Crimson Caravan to earn enough money to continue funding his carousing, but he does not have any loyalty to Crimson. Should the Prisoner approach Mallet about taking him back to Tibbets, then they had better be ready for a fight. Mallet will not go quietly and will begin to punch the prisoner in the face until he is dead.
Mallet McBride has not appeared nor is he mentioned in any published game. He was to appear only in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if he will appear in any future Fallout game.
