Leave the room, don't touch the robots. At the exit, talk to Mr. House. He'll ask you to return. Then, leave and go to Caesar. He'll offer you the choice of what to do with Benny. Then, talk to Benny. Once you've dealt with him, go back to Caesar. He'll say he wants Mr. House dead at your own hands. Use the Pip-Boy to get to the Strip. Head to Lucky 38 in the city and go up to the penthouse. There, give Mr. House the chip. You'll be taken to a basement with a bunch of robots. Talk to House about his plans and continue on with Fallout: New Vegas.
Then read his explanation of how to reach the Bombers' main gate. When you reach the gate, they'll start shooting at you. Wait for a lull. During these moments, quietly make your way to the gate. There, speak with Raquel and the guard. Afterwards, you'll be escorted to Pearl. She'll tell you about the Bombers' problems.
Go to Layal's house to the northwest and talk to him. He needs parts to repair the solar panels.
Head east to the solar panels. Search the area. You'll find battery parts if you haven't leveled up your repair skill. If you have a repair skill of 65 or higher, you can get by without the spare parts. Once you've repaired them, return to Loial and report the news. He's in the Hangar during the day and at home at night.
It's time to speak with Pearl in the barracks to the south. She's sending me to Loial again to discuss the future of the Demolitionists. He'll tell you about the bomber that crashed in Lake Mead. Use your Pip-Boy to travel to Boulder City. Then head northeast to Lake Mead. As you continue through Fallout: New Vegas, follow the marker. You must attach ballast under the bomber's wings. Sail to the northwest shore.
Find the sign that says "Brimstone." Find Cachino and ask around about him. Talk to him. To get the key to his room, go to the entrance and talk to the girl. Once you have the key, go to the elevator and go up to the rooms. Turn left twice and find the room. Open it and go inside. Go up the stairs. There's a table in the corner; open it to find Cachino's journal. Return to Cachino. If he agrees to keep quiet about Omertas' plans, you'll receive 100 caps in return. Fallout: New Vegas continues.
You need to find Troike. Go down to the very bottom level. When you exit the elevator, walk past Ghaul and take the door on the left. You'll find yourself in a hallway with doors. You need to open all the doors until you find Troike in the room with the bandits. He'll ask to be released from his contract with Big Sal. You have three options: if you've leveled up Conversation or Barter, you can persuade Sal to void the contract. If you've leveled up Medicine, you can claim the story is fake. You can also simply search Sal's safe to find evidence.
You'll find a bunker there. Go inside. Go downstairs and stand next to the closed door. Wait for it to open. Run inside immediately. The soldier asks you to leave all your belongings here. Agree. Continue down the stairs and speak with Paladin Ramos at the bottom. He will take you to the elders.
