The Moon Comes Over the Tower

The Moon Comes Over the Tower is a side quest in Fallout: New Vegas.

Quick walkthrough

 * 1) Bug an access point to the Lucky 38's data network for the Followers of the Apocalypse
 * 2) Return to Emily Ortal on the New Vegas strip with news that the tower has been bugged.

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 Hangar in Nellis AFB. She will ask the player 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 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.

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 the reward for selecting (experience, completion of speech towards challenges). This allows the player to get credit for completing speech challenges (the experience points for completing the speech option is only given once however). Note that ending the conversion 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.
 * You can still get the quest after killing Mr. House, it does not change dialogues with Emily.
 * Even if you have installed Yes Man on Mr House's computer system, Emily will still tell you 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 will not be able to access the terminal behind the bar in the VIP lounge. Therefore, the player cannot continue the quest.
 * Once you have bugged the terminal and you exit the Lucky 38 Emily Ortal will not be outside (I have tried on two accounts and same result and i only have an Xbox 360)
 * After bugging the computer I took two steps and Emily appeared in the Lucky 38 seeming to have come out of the hotel's elevator.
 * If the player has not planted the bug in a certain time, Emily will remind him as he leaves a room, including inside the Lucky 38
 * Emily may not appear if you start a confrontation with Victor (by chosing the, I go where I please, speech option when he mentions your companion) when you first meet him in front of the Lucky 38.
 * when doing the quest, if you go to a dlc area before completing the quest, it is possible for her to enter the Dlc area and ask if you've bugged Mr. House's network. and will become trapped in that area. the quest is still completable if you can return to the area. but if you cannot return (such as Dead Money), then the quest cannot become completed. however you can force-fail the quest by killing Mr. House
