Note: This requires a few C4s and a Detonator. In the final part you will enter a vault with 37 gold bars that weigh 35 pounds each. Each gold bar is worth 10.539 Caps. Use the following trick to loot all of them. Enter the vault and the door will seal behind you. Take everything in the room, including the 36 gold bars on the table to your right and the single gold bar on the overseer's desk. Deactivate the security system and activate the computer on the desk. Note: Only read "Vera" and do not access the file that appears after you read it. Elijah will appear on the monitor. Convince him to meet you in the vault. When the conversation ends, immediately leave the now unlocked room. Walk to the far right stairway. A blue force field will appear, blocking your path. Lay your C4 at the bottom of those stairs then press your body against the blue force field in the doorway. When Elijah finishes speaking, you and he will switch places. Make sure he is on or very near the C4. Detonate the C4 and leave the way you came.
