Golden gecko (Fallout: New Vegas)

Golden Geckos are creatures found in Mojave Wasteland. They are like the other geckos of the region, but with shiny golden scales.

Characteristics
Golden Geckos have been affected by high levels of radiation and as such, when they attack you, you will accumulate a small amount of radiation.

Golden Geckos can be found in many irradiated places around the Mojave, most notably around the Crescent Canyon, Clark Field, around Vault 34, and the areas around Camp Searchlight.

Combat
Golden Geckos do significant damage and can easily kill a low level PC. In addition to the radiation effect, they are speedy and attack in groups, and if a follower NPC is attacked by them without PC backup they will usually be killed.

Loot
Golden Gecko corpses contain the unique Golden Gecko hide and occasionally Golden Gecko eggs. Like the normal Gecko and Fire Geckos, they will also provide Gecko meat

Appearances
Golden Geckos appear in Fallout: New Vegas and Fallout 2.

Bugs
Using a grenade machine gun on Golden Geckos will not kill them. Their health bar will deplete, but they are still alive and will still attack when the bar is empty. Even attacking through V.A.T.S will not kill them, but V.A.T.S will display their health bar as being full.
