Sierra Madre Grand Opening!

Sierra Madre Grand Opening! is a quest in the Fallout: New Vegas add-on Dead Money.

Detailed walkthrough
This quest is given to the player automatically after downloading the Dead Money add-on and then, either loading a saved game or stepping out into the Mojave wasteland for the first time.

The Sierra Madre Broadcast radio signal is found which advertises the Sierra Madre casino.

Travel to the abandoned Brotherhood of Steel bunker, north-east of Nelson and south-east of Camp Forlorn Hope to learn more.

Upon entering the bunker, head down the stairs and approach the door ahead of you, attempting to open the door causes a prompt to appear asking whether you wish to continue and commit to traveling to Sierra Madre. Accepting the challenge opens the door.

Walk through the door and approach the radio. The Courier is then knocked unconscious by gas flooding into the room and the player is treated to a slide show detailing the history of the Sierra Madre casino. You will receive an in-game message stating that your companions have returned to their homes.

Upon waking in the Villa, the Courier will find they have been stripped of all useful armor, weapons and aid. The player is greeted by Father Elijah's hologram, which explains that the Courier has been fitted with an explosive collar and that he, Father Elijah, demands the player to recruit three companions in order to carry out a heist for the centuries upon the casino.

After getting all the information you wish from Elijah, end the conversation and you will start the three quests: Find Collar 8: "Dog", Find Collar 12: Christine and Find Collar 14: Dean Domino.
