Tend to Your Business

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

Walkthrough

 * If you are willing to sacrifice Cass, you may kill them all during the botched arms deal to the Legion, then go back kill the doorman and all the Van Graffs have been killed, now go back to the brotherhood bunker and the quest is complete.


 * With a sniper rifle modded with the suppressor equipped, find an area where you are 'hidden' while sneaking, and hit the guards in the head for a one shot kill, that leaves the others unaware. Attacking any named character in this manner will cause all factions members to be hostile toward you, so make sure to kill the guards before you target Van Graffs or Simon.


 * There is a "dead spot" behind the pool tables where you can sit and hide. So with the Incinerator burn them up and run behind the table. Enemies can shoot but they will hit the table and you can still burn them with Incinerator.


 * It is also possible to draw all the guards out into the streets of Freeside. Just setup Plasma mines by the car just before the Silver Rush. Kill the Silver Rush Crier first as he will become hostile. Shoot the door guard with a non silenced weapon and stand 3-4 guards will join from the Silver Rush. Use a powerful rifle as the Van Graff guards are tough, AP ammo works decently well. If you have it, the Archimedes works fantastically here. Once guards are all dead, enter the Silver Rush crouched. Pop a Stealth Boy then, throw a few Plasma Grenades. One guard and the two Van Graffs were left inside use a sniper rifle silenced they do fire back, but are confused for a time.


 * It is also possible to draw all the guards out into the streets of Freeside and make them follow you and enter the strip and wait for them to enter the strip. Then enter the Lucky 38 and they will follow and as soon as they enter the Securitrons will shoot them (if you already upgraded the Securitrons to the mark II, they will use their rockets.) Then you go back and kill Gloria Van Graff and Jean-Baptiste Cutting in the store. (No longer possible in patched version of the game, Securitrons will remain neutral to the guards even when they're shooting at you inside the Lucky 38 casino)


 * Another technique is to use a Stealth Boy while out of sight in Freeside, then enter the Silver Rush and crouch. Once inside and sneaking, go up to the main characters, when you are prompted to pickpocket them plant a frag grenade and immediately start backing up. This will kill them and you can move away from the responding guards to stay hidden. If you have a problem with this, you can run in the back and upstairs out of sight and use another Stealth Boy to escape detection.


 * If you're going to kill the Van Graffs the old fashioned way then use the blast shields around the shop for cover, have your companions take most of the fire, once your companions are dead (and they most likely will die) wait for the Van Graffs to come around the blast shields to shoot at you, when they do it will be really easy to ambush and kill them all.


 * Any one of those above or just walk in, kill them and walk out... Simple, but you need to be in an appropriate level and using high-powered weapon such as Anti-materiel rifle or YCS/186.  Also using Armor Piercing rounds will make killing them all easier.


 * If you Murder the Silver Rush Crier and the Guard out front, you can sneak and use an energy weapon (provided you have the Meltdown Perk) which will get you a Sneak attack critical on all the guards that come out, generally killing them instantly.


 * It is also possible to use their weapons against them. By picking up the mines, grenades and heavy energy weapons on the shelves (using the pick up item key rather than the add to inventory key), it is possible to move items into the shop's toilets where you can steal them out of sight. The plasma mines are particularly useful, as they can be used to mine the approach to the toilets, where it is far easier to defend yourself since guards will have to enter one at a time.
