Detailed walkthrough
During your visit in Nipton you notice that something isn't right. Upon entering, a very strange man who seems to be over-excited about winning "The Lottery" runs into you and keeps repeating that he has won. When you go further into the town, the Legion have taken over the town and killed almost everyone. While searching through the the town, you find a man called Boxcars in the general store. Box car thinks you're going to kill him. His legs are crippled by the Legion and tells you about the sick sadistic lottery that the legion plays with the town of Nipton. The mayor of Nipton had the lottery ticket to be burned in a pile of tires. Boxcars was lucky that he was alive but they smashed his legs, and he is now a cripple. He explains to you that some of the Powder Gang were enslaved by the legion and headed east. He mentions that his legs are very painful and needs Med X. You then have the option to spare some for him (You get a choice of 1, 2, or 3 doses) You head east towards the quest marker. You come across some legion about to get into a fight with some traveling merchants. (You can choose to help the merchants or not) You continue on and you will run into a couple more legion soldiers on the way. You eventually get to the Enslaved Powder Gang members. Kill all the legion soldiers there and untie the slaves completing the quest. (There is no Negative Karma for killing the slaves after the quest is completed)
