Cloud

 is a location in the Mojave Wasteland.

Layout
A massive cloud of toxins, spewed over a deserted cityscape by the air conditioning and climate control systems inside the Sierra Madre. Only the Ghost People walk the Cloud, protected by Hazmat suits.

Effects
The toxic fumes within will slowly deplete your health. Dean Domino has the ability to protect you for a few seconds, and will also offer increased resistance to the negative health effect. Despite allowing the user to breathe in a liquid environment, the Rebreather has no effect in the cloud and you will still take damage.

Appearances
appears in the Fallout: New Vegas add-on Dead Money.
