Get Gizmo's confession

Get Gizmo's confession is a side quest in Fallout.

Detailed walkthrough
After the Vault Dweller speaks to Killian Darkwater for the first time, a shady gunslinger with a hunting rifle will enter the store saying "Gizmo sends his regards!", then attack Killian. Kill the assassin to earn 400 XP plus the regular XP for killing him.

Alternatively, talk to Gizmo and accept the "Kill Killian" quest. Instead of going through with it, talk to Killian and mention it when asking about Gizmo. The quest should continue as normal; this may be your only option if you didn't assist by attacking the assassin.

Killian then asks the Vault Dweller to get a confession from Gizmo so he can imprison or kill him. If accepted, Killian gives the Dweller a bug and a tape recorder.

The player character should proceed to Gizmo's casino. At this point they can:


 * 1) Plant the bug on Gizmo (Steal skill).
 * 2) Persuade Gizmo to explain why he wants Killian dead, while the tape recorder is in their inventory.

Regardless of the option chosen, the Vault Dweller must return to Killian to get his reward. The method used does not alter the reward.

Rewards

 * 500 XP
 * An item of merchandise from Darkwaters General Store:
 * Five stimpaks
 * A doctor's bag
 * Leather armor
 * shotgun with 100 shotgun shells
 * Killian offers the Stop Gizmo quest.
