Bust the Skulz gang

Bust the Skulz gang is a side quest given by Lars to put an end to the Skulz gang and their crimes in Junktown. Lars asks the Vault Dweller to get evidence or a testimony of the Skulz' illegal activities that will put them in jail for good.

Violent solution
The Vault Dweller witnesses an incident at the Skum Pitt when a Skulz member is killed by the proprietor, Neal, for harassing his employee. (Note that this event will only happen in the evening.) When spoken to, Vinnie (the leader of the gang), asks them to steal Neal's Urn as proof of loyalty. Stealing the urn and showing it to Vinnie grants 400 XP and a small Karma drop. (One has the option to return the urn later to gain more Karma than what was originally lost.)

The Vault Dweller is then given the choice to help the Skulz exact revenge on Neal and Trish, which grants 300 experience points, but makes every guard in Junktown turn hostile. If the Vault Dweller tells Vinnie that they need time to prepare, they can tell Lars what is happening, and help the guards attack the Skulz during their assault on the bar. The player character receives an additional 500 experience points when they speak to Lars after the fight.

Peaceful solution
The Vault Dweller can also solve this quest by convincing Sherry to leave the Skulz and testify against them. In order to do that, the player character should talk with Sherry, and convince her that there is no future for her in the Skulz.

One day later, Sherry will move to the southwestern part of the Crash House hotel. She will tell the Vault Dweller that she has left the Skulz and that she has begun a new life as a cook in the Skum Pitt and in the Crash House. At this point, the Vault Dweller can convince her to testify against the Skulz.

After the Vault Dweller has convinced her, they need to pay a visit to Lars and tell him that Sherry is willing to testify. This completes the quest.
