Strictly Business

 is a Fallout 3 quest. It is also a PS3, Xbox 360 and PC achievement.

This quest will begin the first time you approach Paradise Falls.

Grouse will address you and tell you that you cannot enter Paradise Falls unless you have business there. He will offer to let you in only if you go and enslave select people from his VIP list. He will split half the profit with you for each person. You will be allowed into Paradise Falls after you have enslaved at least one VIP. If you attempt to enter Paradise Falls by walking past Grouse and the other gate guard before you have enslaved at least one person off the VIP list, you will hear the the other gate guard give you two verbal warnings to leave (without entering into dialog mode with you). If you are still inside the gate a short while after that second warning, Grouse and his associate will attack you, which will make all of Paradise Falls hostile. Alternately, you can pass a speech or karma check to enter Paradise Falls, however this does not prevent you from doing the quest. This quest involves enslaving several characters for the slavers of Paradise Falls. Enslaving is done with the Mesmetron and a slave collar, which you will get from Grouse. Along with it come the notes Slave Collar Instructions and List of "recruits" for Paradise Falls as well as the holotape Mesmetron Manual - Summary Page. Make sure to return to Grouse after each slave to collect a new slave collar for the next one.

Your VIP List
The characters that have to be enslaved for the slavers are the following:
 * Flak from Rivet City
 * Red from Big Town
 * Susan Lancaster from Tenpenny Tower
 * Arkansas from Minefield

If Red, Susan, or Arkansas are dead before the quest is given, they will not appear on your list, and Grouse will allow you to enter Paradise Falls. Flak can't be killed before the quest.

Arkansas
Arkansas is sniping from a ruined building in Minefield. Be careful as you make your way through the town, as land mines are scattered all over the town. Cars also will be shot at by Arkansas and can kill you. (Note: If you Kill Arkansas before obtaining this quest, he will not be on the VIP list.)

Susan Lancaster
Susan Lancaster may be found on the top floor of Tenpenny Tower in her penthouse suite (at night). Simply shut the door, mez, and collar. If you have found the note left in her room revealing the possible affair between her and Edgar Wellington II and then show it to Millicent Wellington, Millicent will kill Susan and you will not have to enslave her. If Susan is your last target, the quest will be completed as soon as she dies.

Red
Red can usually be found in her clinic. If she's not there try walking around a bit and then enter her clinic again. If you did not complete the Big Trouble in Big Town quest yet, Red is captured by super mutants and held in the Germantown police station. You can simply enslave Red there, but it will prevent you from completing the Big Trouble in Big Town quest unless you rescue her from Paradise Falls later. It is possible that she gets killed by a super mutant attack after completing Big Trouble in Big Town and you will not have to enslave her.

Flak
Flak can be found in his room on the Upper Deck (at night), and is probably the most difficult VIP to capture. One strategy that can be used: Wait outside his room until about 10pm then follow him to the dead end by Doctor Li's room. Make sure there are no guards, then mezz him. Exit stage right into the lab before he sees a guard. You should be safe after this. Another strategy (If you are doing the quest for the achievement only) is to save, mezz Flak anywhere in Rivet City, flee the city, finish the quest to earn the achievement, and reload from the previous save.

Bugs

 * If you enslave and order a victim to go to Paradise Falls, and then die/reload previous save, the character you've enslaved before you reloaded the save may appear in the Paradise Falls slave pen, without a slave collar on, and with all of the dialog options they normally had (for instance, you can still trade with Flak in the slave pen if he does not have a slave collar). Reloading the save will not fix this problem every time, so you may have to somehow get the target to come near you in the slave pen where you are able to Mesmerize and fit a collar onto the target. If Arkansas was the target, he will pull out his sniper rifle and begin shooting everyone around him.


 * When mezzing a person in V.A.T.S. with the Mysterious Stranger perk active, the Mysterious Stranger may appear. The Mysterious Stranger will look and move around, but no gun shots will be fired. If there is another enemy close by, however, the Stranger will shoot them instead.


 * You may be able to get paid two times for each of the VIP slaves you get. After getting paid the normal money when you reach Paradise Falls you can pickpocket a key to the slaves pen. Upon talking to all of the VIP slaves you captured and returning to Paradise Falls entry Grouse just repeats the speeches as if you just got the slaves and pay you again.


 * If you enslave Flak, Shrapnel may disappear from Rivet City. He will return only once in a long while (every few days/weeks). He can be seen wandering the wastes and even in Paradise Falls likely looking for Flak. Apparently, Shrapnel's wandering after you enslave Flak is caused by an AI script that says the two should sleep near one another. Enslaving Flak thus causes Shrapnel to wander the wasteland trying to get to him.
