Brahmin (Fallout 3)

Brahmin are two headed creatures found in the Capital Wasteland in 2277.

Background
Brahmin have been domesticated throughout the years since the Great War. Some brahmin can be seen wandering the Wasteland, but this is rather rare. Through their domestication, they have been used primarily for meat, milk, and their hides which are tanned to make leather. Traders often use them as pack animals. The Capital Wasteland Brotherhood of Steel uses them to distribute clean water to the wasteland after Project Purity is launched.

Biology
It would seem the radiation has tried to force the brahmin into two separate organisms. As a result of the constant radiation, these formerly normal cows have sprouted a second, independent head. Ironically, when brahmin are born with a single head, they are considered mutated. Brahmin also have eight stomachs. When talking to Rose, it is revealed that brahmin also have four testicles. Their skin has turned a toasty, dusty orange to red color from the fallout exposure and their horns have in turn become a dirty brown. Their udders have also grown abnormally large (almost dragging on the ground) and brahmin milk is used by Moira Brown as part of a recipe to cure radiation.

Gameplay attributes
Brahmin are low level creatures and can be little more than a nuisance in the beginning of the game, if you can even find one that's hostile. In fact, most brahmin throughout the game are non-hostile and will only attack if provoked. When they attack they run and ram into foes, swinging their horns into the body of the threat. Though their hide is thick, bullets will still penetrate and kill them rather quickly. If you attack them they will turn hostile and become a mad brahmin and charge right at you so if you are unprepared or if you dont have your weapon on hand its better to shoot as soon as possible to one of the three heads. After the Brahmins death you will be able to consume the meat and gain hp.

Brahmin
Brahmin are the the only bovine in the game, mostly being seen in makeshift settlements like the Republic of Dave, Megaton, and Arefu. You will seldom see them as enemies; however, if you do come across a hostile brahmin, you needn't worry as they are easy to dispatch.

Mad brahmin
Mad brahmin are brahmin who have gone insane. It is not known whether the brain degeneration is from radiation or from a disease, but one thing is for sure: they will be hostile to any player without the Animal Friend perk. They are also fairly easy to kill and usually found in groups.
