Karma (Fallout)

Reputation in Fallout is the reflection of what people think of the character based on their actions. In addition, the Vault Dweller can be given various location-specific reputation titles.

Positive

 * +1 for talking to the cook in Shady Sands, complimenting her by passing a Luck check.
 * +10 when leaving the exploding Cathedral.
 * +5 when starting the destruction countdown of the Mariposa Military Base and +5 leaving the exploding base.
 * +2 when returning to Irwin in the Hub after clearing his house of raiders.
 * +5 for finding out what happened to the missing caravans and explaining how mutants were the cause.

Negative

 * Each time one is sent to jail in Junktown for any reason, the fine is 100 caps and -1 to reputation. Not having the funds to pay the fine gives -3 instead.

Effects

 * Improve Garret's check reaction for rewards in the quest Destroy the Super Mutants at the Watershed.
 * With 16 reputation or higher, one can choose a reward for completion of the quest Rescue Initiate from the Hub.
 * With -2 or less during the confrontation with the Vault 13 overseer at the end of the game, the Vault Dweller automatically draws a pistol and shoots him (with a violence setting above "normal").
 * With -21 or less in the random encounter with Trent Barrister, one can tell him to hand over his things, which grants a knife, a Desert Eagle, 20 rounds of .44 Magnum FMJ & JHP each.
 * With IN < 4, a reputation between -30 and 29 and not being a Childkiller, during the random encounter with the weary fisherman, he will give a Rad-X.
 * With +20 or above, and if already having discovered Lost Hills, during a random encounter with Brotherhood of Steel paladins, they can be asked for an escort to Lost Hills.
