Mysterious Stranger

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

Fallout and Fallout 2

 * Requirements:
 * Fallout: Level 6, LK 7
 * Fallout 2: Level 9, LK 4
 * Ranks: 1
 * Benefit: 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 armour. (52 HP if stranger is female)
 * 15-18: 70 HP, combat leather jacket.
 * 19-22: 90 HP, metal armour mk II.
 * 23-26: 110 HP, combat armour mk II.
 * 27-99: 130 HP, power armour.


 * 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

 * Requirements: Level 10, LK 6
 * Ranks: 1
 * Benefit: 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. 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.

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.
