Mysterious Stranger

Mysterious Stranger is a Fallout, Fallout 2, and Fallout 3 Perk.

Fallout and Fallout 2
When you select this perk, there is a chance (30% + (2x Luck)) that your character will gain a temporary ally, but only in random encounters.

Details depend on the player's level:
 * 9-14: 50 HP, leather armor. (52 HP if stranger is female)
 * 15-18: 70 HP, combat leather jacket.
 * 19-22: 90 HP, metal armor mk II.
 * 23-26: 110 HP, combat armor mk II.
 * 27-99: 130 HP, power armor.


 * 9-13: Hunting Rifle or FN FAL.
 * 14-19: Assault Rifle or Combat Shotgun.
 * 20-26: Laser Rifle or H&K CAWS.
 * 27-99: H&K G11.

Fallout 3
You've gained your own personal guardian angel... armed with a fully loaded .44 Magnum. With this perk, the Mysterious Stranger will appear occasionally in V.A.T.S. mode to lend a hand, with deadly efficiency.

If you can get an opponent down to 150 health or less in V.A.T.S., there is a 10% chance the stranger will show up and finish them off with his highly accurate magnum (His shots can still hit team mates or obstructions and not kill a target), regardless of whether you can still see them or if you hit. Also could be considered adding a critical chance to V.A.T.S. Quite humorously, the Stranger still appears next to the target even if you are using a Fat Man. Luckily he can only be knocked out(clarification needed). Unfortunately, neither Lawbringer, Contract Killer, or Grim Reaper's Sprint will grant their benefits, because you did not make the kill.

His appearances have a counter called 'Mysterious Stranger Visits' that is displayed during the loading screen of the game and on the Pip-Boy 3000 under the Stats tab - General.


 * Note that his magnum does 9000 damage per a shot and should kill any enemy in one hit. (Confirmed: This includes even Super Mutant Behemoths.)

Bugs

 * A rare glitch might occur when the Stranger appears. If the Stranger appears behind the player character or even your possible Follower, he might actually murder all of you. This has happened to a few players on occasion, but is only most common in small confined spaces, such as a house in Megaton.


 * The Stranger can also fail to kill a character or creature.


 * During VATS it is not uncommon to hear the Mysterious Stranger music, even if he does not appear.


 * It is possible to kill the mysterious stranger should he appear between you and the target while firing in V.A.T.S. Generally this will occur in small spaces, perhaps in a small silo somewhere near the Republic of Dave while a mohawked raider bludgeons you with a lead pipe. The mysterious stranger will not reappear should this happen(clarification needed).


 * On the PS3 version, if the mysterious stranger appears whilst you are using VATS at a distance with a sniper rifle the display will corrupt and the game will freeze. Best way round this is to save before you use VATS with a sniper rifle.
