The Moon Comes Over the Tower

The Moon Comes Over the Tower is a side quest

Detailed walkthrough

 * Speak to Emily Ortal near the entrance to the Lucky 38 to begin the quest. She may also appear in the House Resort near Camp Golf (using wait option just inside) and also has been known to appear when the Courier leaves the Nellis hangars and when the Courier finishes Lonesome Road. She will ask the player character to bug Mr. House's mainframe. (If she doesn't appear outside the Lucky 38, the player needs to progress further in the main quest line. The player needs to deal with Benny or initiate combat in The Tops in order to get Emily to appear.)
 * Enter the Lucky 38 casino.
 * Entering the main casino, turn left and head up the stairs to the VIP lounge.
 * Activate the terminal behind the bar.
 * Choose the option to bug the network.
 * Head back outside the casino. Emily should be at the bottom of the stairs or immediately to the left (near the gate to the next part of the strip).
 * Tell Emily you bugged the network, she will tell the player character that this data "might come in handy".
 * However, after that, the reports stop coming in (due to Mr. House removing the bug).
 * After Emily Ortal has been informed that the bug has been removed, she will still be thankful, and your reputation with the Followers of the Apocalypse will be raised.
 * With a Barter of 40 or higher, one can get her to give them some medical supplies.

 * Followers of the Apocalypse fame

 * 2 doctor's bag
 * 2 Med-X
 * 2 Jet
 * 5 stimpak

 * 2 Today's Physician

Behind the scenes
"When the Moon Comes over the Mountain" was a popular song published in 1931 and written by Howard Johnson, Harry M. Woods, and Kate Smith.

Bugs

 * After completing the quest Emily will remain outside the casino and you can talk to her to learn about the first attempt on hacking Mr. House's network. A 35 speech level dialogue option eventually becomes available that will remain in the dialogue list even after granting the player character the reward for selecting (experience, completion of speech towards challenges). This allows the player character to get credit for completing speech challenges (the Experience Points for completing the speech option is only given once however). Note that ending the conversation will block any further communication (and thus exploitation) although Emily will remain in front of the Lucky 38.
 * Emily may enter the Lucky 38 to present this quest, when doing Act II before doing Act I.
 * One can still get the quest after killing Mr. House, it does not change dialogues with Emily.
 * Even if one has installed Yes Man on Mr House's computer system, Emily will still tell the player character Mr. House disabled the bug 30 seconds after installing it.
 * This quest can be given twice, but the second time the quest is given the player character will not be able to access the terminal behind the bar in the VIP lounge. Therefore, the player character cannot continue the quest.
 * Once the terminal has been bugged and the player character exits the Lucky 38, Emily Ortal may not be outside.
 * After bugging the computer, Emily may enter the Lucky 38 casino to ask the player character if they have completed their task. She may even enter the presidential suite.
 * If the player character has not planted the bug in a certain time, Emily will remind them as they leave a room, including inside the Lucky 38.
