Geckos can be found living across the entirety of the Mojave Wasteland, with many different species calling the local area their breeding grounds. There are three types of gecko in the Mojave: the normal gecko, the golden gecko, and the fire gecko. Another variety, the green gecko, is found in Zion Canyon in the Fallout: New Vegasadd-on, Honest Hearts.
Geckos in general are reptilian, and are normally born with a pair of fins behind their heads. Their eyes possess an orange tint, and their body colorations differ greatly based on the gecko sub-species present. Geckos have evolved with five fingers and five toes.
Geckos are generally found in small packs. They charge/leap at their opponents with their mouths open ready to snap down, along with being known to simply attack with their claws rapidly. Some sub-species of geckos can breathe fire or spit poison, so that they may also attack from a distance.
Their hides can be tanned, and used to craft several varied types of armor, which offers greater defense than their base variants.
Geckos, green geckos, and golden geckos, are affected by the Animal Friend perk. Fire geckos, however, are an exception to this rule.
Geckos appear in small to large packs depending the location. They will charge at their prey with their mouths open, and attack by biting and with swipes from their clawed hands. Geckos can be found mostly in the areas surrounding Goodsprings, and along the I-15 towards Primm and the Mojave Outpost. These are the least dangerous species of gecko found within the Mojave.
A type of gecko with brilliant golden scales. They can be found around irradiated areas such as Crescent Canyon east and Crescent Canyon west, Vault 34, and Cottonwood crater. Golden geckos have been affected by high levels of radiation, causing their larger sizes and unique colorations, along with an addition of causing large amounts of radiation with their attacks.
Fire geckos have mottled purple and red hides, and prominent spikes on their backs. In addition to their bite and claw attacks, they have the ability to breathe fire. They can mainly be found in and around mountainous areas and caves, such as the Lucky Jim Mine and Nopah Cave.
The legendary fire gecko is one of several legendary creatures. It is roughly twice the size of a normal fire gecko, and its powerful and fast attacks makes it a potentially dangerous opponent in close combat. It can be found in Fire Root cavern.
Green geckos are native to and only found in Zion Canyon. When attacking from a distance, they can spit several far-reaching but slow-moving globs of poisonous saliva, somewhat resembling the radioactive spit attack that centaurs use. Once in contact with an enemy, they will attack like other types of gecko, by biting and clawing. Green geckos are almost always found in packs ranging from two to eight. Green geckos are often found near waterways and bridges in Zion Canyon.
Several friendly geckos appear in the main Sorrows camp in Honest Hearts. They are friendly, possibly tamed.
Geckos do heavy damage to limbs, especially the head.
Another type of fire gecko exists, but was cut from the final product. Its name is Gojira. Simply called "gecko" when spawned, Gojira is its editor ID. It's identical to the fire gecko, but about triple the size and has a whopping 8,000 hit points.
pcps3xbox360 Geckos may not always be hostile to the Courier, even if the player doesn't possess the Animal Friend perk. However, getting too close or trying to speak to one may turn it hostile. [verified]
xbox360 Green geckos inhabiting Zion may not be hostile to the Courier, and approaching, or attempting to talk to them will not change their disposition, if you happen to shoot one of these geckos, simply put away your weapon and it will return to being friendly, just like a normal non-player character.

xbox360 In the Mojave Desert, several young gecko hunters may be found superimposed upon one another, but not moving from the spot except to flail their arms and roar loudly. They cannot be damaged with guns, and when attacked and killed with a melee weapon, the game freezes and must be reset. [verified]
