1. If you give the information to Hildern but Keelie Dies: NCR's OSI takes no precautions with the technology and swiftly repeats the mistakes of the past.

Thomas Hildern blames his assistant for taking inadequate precautions with the materials and she is executed by the NCR.

2. If you give the information to Hildern but Keelie Lives: NCR's OSI is warned about the dangers of the Vault technology and proceeds cautiously with the material.

Thomas Hildern takes full credit for the miracle and is named Director of the OSI.

3. If the information is shared with the Brotherhood of Steel [only if the Brotherhood is not destroyed]: Though usually uninterested in non-military technology, the Brotherhood discovers the technology is highly useful given their underground existence. Hundreds of new bunkers are created with hydroponics gardens, allowing them to expand their numbers tremendously. Underneath NCR and the Mojave, the Brotherhood builds an empire.

1. The Omertas succeed in their plan (Caesar's Legion - the White Glove Society is not turned into cannibals - Caesar Lives): The Omertas successfully seize control over the Tops and the Ultra-Luxe, slaughtering their inhabitants. When Caesar's Legion arrives, they welcome him into the city with open arms. Caesar rewards them by making them New Vegas' ruling class, forcibly converting them from prostitution and gambling to slavery. The Omertas, with only mild reluctance, accept his change.

2. The Omertas succeed in their plan (Caesar's Legion - The White Glove Society is turned into cannibals - Caesar Lives: The Omertas are informed by Caesar's Agents to spare the Ultra-Luxe and instead focus their attention on visiting NCR tourists, Vault 21, and the Chairmen. The streets run red with blood and the Omertas are there to welcome Caesar's Legion into the city alongside the White Glove Society. Adopting slavery instead of vice as their new job, they soon become rivals with the White Glove Society for the rulers of New Vegas.

3. The Omertas succeed in their plan (Caesar's Legion - Caesar dies): Though the Omertas make the city streets run red with blood, they are not rewarded the way they expected by Legate Lanius. Disgusted by their cowardly attack on the Strip, he makes their deaths especially painful. The Gomorrah was then burned with its prosttutes, a lesson in the dangers of hedonism.

4. The Omertas succeed in their plan (Yes Man): The Omertas murder most of their rivals during the Battle of Hoover Dam, rising to unparalleled power amongst the New Vegas families.

5. The Omertas are thwarted (NCR Victory - Cachino Lives): NCR's rulership and anti-slaving laws severely cut into the Omertas business but the boom in tourists from the West more than makes up for the loss.

6. The Omertas are thwarted (House Victory - Cachino Lives): Mister House's victory reminds the Omertas of who really is in charge. Cachino runs the Gomorrah strictly according to Mister House's wishes, eventually opening up a second and third casino as time passes.

Eventually, stress over his performance results in Cachino giving himself a fatal overdose.

7. The Omertas are thwarted (Legion Victory): Caesar/Legate Lanius is unimpressed with the Omertas performance. When they arrive on the Strip gates, the family is crucified and their prosttutes are either put to the sword once they are discovered to be addicted to chems. The Gomorrah is left as an abandoned ruin, serving as a lesson to Profligates to the dangers of hedonism.

8. The Omertas are thwarted (Yes Man - Cachino Lives): The defeat of Mister House convinces Cachino he made the right decision by supporting the Courier.
