The Brotherhood of Steel is aware that there's a bunch of good technology lying around in the Burham Springs mines. They want to prevent it from being distributed throughout the wastes by Phil, Sparky, and Frank. The core BoS does not want anything done to those three, but they do want to reclaim as much of the old tech as they can. However, the Circle of Steel has different plans. Even if you recover all tech from BoS, the CoS wants Phil, Sparky, and Frank dead. They also want to see the mines blown up via the placement of charges at specific locations in the mines.
Character type completion breakdown
- Combat Boy, Stealth Boy - This is a fairly straightforward quest. The PC simply has to kill Phil, Sparky, and Frank, then set two charges at the entrance to the mines (next to two clearly marked supports). Destroying the supports causes the cave complex to collapse. If the PC is inside, it's game over. Otherwise, the screen shakes and a huge cloud of smoke emerges from the mine. After the smoke clears, there's only rubble in the entrance (any quest items inside are at the edge of the rubble).
- Diplomacy Boy, Science Boy - There is no completion path specifically for these character types.
