Giant Rat (Fallout: New Vegas)

Giant rats are creatures living in the Mojave Wasteland in 2281.

Biology
Giant rats appear to simply be larger versions of normal pre-War rats. The giant rats in Fallout: New Vegas appear to have lost most of their fur (likely to radiation), and have slightly-glowing turquoise eyes. Like normal rats, they also have very large incisors. Giants rats are often found in darker areas, such as Cerulean Robotics and broc flower cave.

Gameplay attributes
Giant rats will not attack on sight, but will stand defensively in the way bighorners do when the player is spotted. Only when the player draws too close or attacks them will they become hostile. Certain examples, such as the giant rats found in Freeside, who will not attack the player regardless of whether or not it is attacked. As with most mutated animals, giant rats will not attack if the player has the Animal Friend perk. Giant rats are also susceptible to, and count towards, the Animal Control perk. Occasionally they will make a sound that resembles a short howl.

Giant rat
These are light brown color, with glowing blue eyes and white hair on its back. The standard giant rat is equal in size to a mole rat. They are normally quite fast and attack in groups of 3 to 7.

Giant rat pup
These look identical to fully grown giant rats, but are smaller than the standard giant rat. They usually don't attack but instead run away.

Rodent of unusual size


Found in the broc flower cave and New Vegas sewers, rodents of unusual size are the largest of the mutated rats found in the Mojave Wasteland to date. They are identical to their giant cousins, save for their increased size and attack strength. They are aggressive and will attack on sight, unless the player has the Animal Friend perk.

Unnaturally large sized rodent
These are uniquely large giant rats, with only two in existence in 2281. They are found in the east central sewers in the same room as "Sweet" Jill. They are identical in appearance, except for size, to their smaller cousins. They are, however, far more aggressive and will attack the player on sight along with any nearby mutated rats, unless the player has the Animal Friend perk.
