Tend to Your Business

Tend To Your Business is a side quest in Fallout: New Vegas.

Detailed walkthrough
After Elder McNamara is ousted and Head Paladin Hardin becomes the new Elder, you are given the opportunity to join the Brotherhood of Steel through a heroic act. Hardin already has a task in mind; to wipe out the Van Graffs as a show of loyalty to the Brotherhood.

Methods of Madness
Due to well-equipped guards, and a mandatory pat-down upon entering the Silver Rush (the Van Graff base of operations) killing all of the Van Graffs can be a difficult task. However there are multiple ways to kill them.


 * Killing Simon the door guard allows the player to enter the Silver Rush without surrendering their weapons.
 * Weapons can be obtained inside the store though either theft or by buying them.
 * During Birds of a Feather the fourth and final customer will attempt to blow the store up and, if allowed in, will result in the death of all Van Graffs, with the exception of Simon. However, this also results in the destruction of much of the merchandise as well.

Conclusion
After eliminating the inhabitants of the Silver Rush, return to the Hidden Valley Bunker. Once there, inform Hardin that you have completed his task, and he will reward you with full membership into the Brotherhood of Steel, rewarding the player with a suit of T-45d power armor and a T-45d power helmet (a formal ceremony would apparently be inappropriate). In addition, the player receives the Power Armor Training perk, if they do not have it yet.
