 is a quest in the Fallout: New Vegas add-on Dead Money.

Quick walkthrough
Where is the Holotape Projector?

- The Holotape Projector is up a staircase, overlooking the stage. If you are facing the stage, the staircase is to the right of the stage.

Where is the key to up stairs? The key is in Vera's Partitures paper music in front of the stage.

Where is the last holoprojector for the Hologram guard that patrols the stage? There is one right in the entrance hallway to the backstage, another one hidden behind a couch in the storage room backstage, but where is the third and final projector? After activating the projector the holograms disappear.

Do you have to kill Dean once you talk with him backstage? No you don't have to

Detailed walkthrough
Enter the theater area and you will have a desk with a computer and cash register in front of you, the computer can be hacked to discover the Tampico's listings of how the show operates and there is also the Sierra Madre security code (which you will already have). Upon moving forward you shall see the main doors, with a skeleton and the Tampico's desk terminal password, which are inaccessibility and two paths that lead left and right, the path to the right has a vending machine at the end whilst the left has a skeleton. Both paths will make your collar beep, but on the right hand side path the door will be locked, so go to your left and your collar will beep and just at the entrance of the door frame above you to your right is a speaker, blow it up.

Now your in the theater where your collar will proceed to beep once you enter but the speakers can't be destroyed as they are secured ones. If you enter from the left there will be a desk to your immediate right and there is a safe which is very easy but only contains Pre-War money and Sierra Madre chips and there is also a first aid box with 2 Dirty waters,a RadAway and 1 Rebound. There is also a random selection of wines, whiskeys and Scotch. So if you head to the middle of the room beneath the stage there is a music stand with some mentats and purified water next to it, this is a safe spot from the beeping. Grab the music sheet (known as Vera's Partitures) and you will have the backstage key and then you'll engage in conversation with the man himself, Dean domino. After a quick talk with him you discover he wanted to rob the casino along time ago, it is possible to pass a speech check here of 65. He says you can't escape and activates three security holograms, one directly in front on the stage and two to either side of you, whilst none of them notice you straight away, make straight for the corner in the right hand side of the room where the backstage door is.

In this corridor there are minor spots of poisonous gas but are avoidable, move forward and to your left to discover Deans room with a radio in which you should turn off, but be careful because your collar will keep beeping so run back to where you entered the corridor and straight again. Run just passed Dean's room and round the corner to see some skeletons, turn around 180 degrees and you will see a speaker shoot it, and then return back to Deans rooms where on his desk you will find Vera's key and his safe. Run to the next room where you will encounter a dummy, this is the backstage props room there is a speaker in this room. The speaker is as you enter on the wall to your left, but if you cant see it run to the middle of the room and face the door you just entered and it will be above a crate standing on its end. In the corner of the room there is an emitter behind a couch which you need to deactivate. As you leave the room the collar will beep again and you will need to find Vera's room for the final radio which is in the corner to your right, in this room there is also a song for Vera by dean take the holodisk on the same table as the radio and the key. the key works for Vera's Med box in her bathroom.

Go back into the theater and from the locked door mentioned early, go forward and then right up the stairs to the projector room, make sure you have Vera's master key and there is a lying Congressional style. Activate the projector with the holodisk and the security will disappear. Go backstage again and the stage door opposite Vera's is open now so go in and climb the stairs and find Dean and speak to him and let him speak about killing you, you can pass a speech check of 75 to convince him for the key to the exit but unfortunately you need to kill him for the key. Then finally run for the exit as killing Dean results in his collar been activated and you must escape the room to save yourself. you have about a minute to do so. (Note, you will not see the key on the body of Dean, it will be immediately added to your inventory.)

Note: It is possible to save dean you just need to avoid the more confrontational speech options.

Journal entries
if someone figures out how to save dean please write it in: It's as simple as walking away.

Edit: I don't know if it works, but it's possible that if you have the perk confirmed bachelor You'll have a speech option with him, wich can save him. I don't know if it works, because I haven't tried it. If someone has the perk and talks to him, please tell if it worked.
