From The Vault
Take down Decker is an unmarked quest in Fallout.
[edit] Walkthrough
After taking one one (or both) of Decker's quests (Dispose of Jain and/or Dispose of merchant, you can choose to report Decker's crimes to the Hub Police. Sheriff Justin Greene will offer you this unmarked quest, promising 300 caps upfront, and 1000 caps upon completion of the quest.
The Vault Dweller's party (now including Sheriff Greene and Deputy Tony Fry) now fast travels to the Basement of the Maltese Falcon for an intense confrontation with Decker and his staff.
- This quest is not marked on your Pip-Boy.
- It is advisable to take Kane out in the Maltese Falcon before taking on this mission, as he can make the close quarters combat extremely difficult and will very probably kill your recruited NPC(s).
- After killing Decker, some or all of the remaining guards may surrender. They can be found later in the Basement of the Falcon. If engaged in combat again they will most likely repeat "I surrender!" once again.
