|The following is based on Fallout Tactics and some details might contradict canon.|
Little is known about this organization. It seems like it is some sort of a raider gang operating not far from Quincy. Some of the Quincy citizens may start to consider forming alliance with Marks Brothers instead of the Brotherhood if the Warrior does not show much success in fighting beastlords.
The Marks Brothers are mentioned only in Fallout Tactics.
Behind the scenesEdit
Marks Brothers is a reference to the comedy troupe Marx Brothers.
