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, Kenji will enter the store wielding a hunting rifle saying "Gizmo sends his regards!" and 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 the only option if the player character did not 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 Vault 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 their reward. The method used does not alter the reward.

Rewards

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