Cloud



The Cloud is a massive blood red blanket of toxins, spewed over a deserted cityscape by the air conditioning and climate control systems inside the Sierra Madre Casino.

Background
It's not exactly clear where the Cloud came from. During the construction of the Villa, construction crews discovered the gas backed up in the Sierra Madre's ventilation system, and attempted to inspect it. Even trace amounts of the gas proved to be harmful. Hazmat suits were ordered in by the workers with the hopes that it would protect them. Unfortunately this wasn't the case, the workers were still exposed to the Cloud and the fastenings of the suits were corroded, trapping the exposed workers inside to the point where they had to be cut free with a cosmic knife. The exposed workers were sent to the medical district, and concerns were raised about the gas building up beneath the streets.

Two hundred years after war, the Cloud completely engulfs the casino, somehow preserving it despite the decades of disuse. Elijah sees the potential for this, and wants to use the Cloud in his new world, using it to preserve and cleanse old world technology. He also plans to use it as offensive technology, unleashing it upon the Mojave, cutting it off. He could then use modified REPCONN rockets to wipe out the New California Republic (NCR) at Hoover Dam, and finally let traces of it it drift west to NCR territory, killing outlying communities there.

Characteristics
The Cloud slowly depletes the health of visitors to the Sierra Madre, and concentrated pockets of it will deplete health far more quickly. Only the Ghost People walk the Cloud, protected by ancient hazmat suits fused to their bodies. God remarks that the cloud tastes of copper and "old world gold."

Note:The rebreather and power armor will offer no protection from the Cloud.

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