Karma

Generally, Karma (as a tab on your in-game character sheet) is the reflection of all good and bad choices you make during the game. In the first Fallout, it only covered a statistic called "Reputation", as well as the special Karma/Reputation perks. In Fallout 2, what was originally called Reputation was renamed to Karma, and Reputation became a measurement of how you are perceived by various communities.

As a statistic, Karma (Reputation in the original Fallout) is a measurement of your good or bad deeds and how they are perceived by the inhabitants of the wasteland.

Wanderer
You start off with the status of a 'wanderer' with 0 karma points. This Status can therefore also be called Neutral. You stay a wanderer until you either reach +250 or -250 karma points.

Defender
If your positive karma reaches 250 you gain the status of the 'Defender'.

Shield of Hope
If your positive karma reaches 481 you gain the status of the 'Shield of Hope'.

Guardian of the Wastes
If your positive karma reaches 751 you gain the status of the 'Guardian of the Wastes'.

Savior of the Damned
If your positive karma reaches 1001 you gain the status of the 'Savior of the Damned'.

Betrayer
If your negative karma reaches -250 you gain the status of the 'Betrayer'.

Sword of Despair
If your negative karma reaches -481 you gain the status of the 'Sword of Despair'.

Scourge of the Wastes
If your negative karma reaches -751 you gain the status of the 'Scourge of the Wastes'.

Demon Spawn
If your negative karma reaches -1001 you gain the status of the 'Demon Spawn'.

Fallout 3
Karma is the system in Fallout 3 that keeps track of the moral actions and consequences of a character. Karma is the principle of cause and effect, and it represents the player's aptitude towards a certain status: good, neutral or evil. Although it is measured in points, the player never gets to see a numerical karmic value, only the title. You can only use the console command player.getav karma to get the current value of karma.

People will behave differently toward you depending upon your karma. For example, if a player has very good karma in Megaton, one NPC will talk to the player everyday to give them free items such as ammo, food or medicine. Players with evil karma can get the same benefits in Paradise Falls.

You begin the game with a value of zero, which increases or decreases based on the players actions. There are 5 levels of Karma:


 * -1000 to -750 : Very Evil
 * -749 to -250 : Evil
 * -249 to +249 : Neutral

Ways of lowering and raising karma in Fallout3



 * Killing an Evil character or creature: +0 karma
 * Killing a Very Evil character or creature: +100 karma
 * Killing a Neutral or Good creature: -25 karma
 * Killing a Neutral or Good character: -100 karma
 * Stealing from a non-evil character or faction: -5 karma per item
 * Donating caps to any church: +1 karma per cap
 * Devour a corpse (Cannibal Perk required): -1 karma per corpse
 * Giving away Purified Water to beggar characters like Carlos outside of Rivet City: +50 karma per item
 * NOTE: There's a flaw to this concept. For example your Megaton house robot Wadsworth gives you free Purified Water and the beggar for water is conveniently posted outside of Megaton. This is pretty much infinitely free positive karma.
 * Giving away Scrap Metal to Walter in Water Processing Plant, Megaton: +10 karma per item
 * Performing a good action in a freeform quest: At least +50 karma
 * Performing an evil action in a freeform quest: At least -50 karma
 * Repeatedly hacking a locked terminal (Classifies as stealing, but can be done over and over again)" -5 Karma per hack attempt
 * NOTE: There is a small bug that allows you to gain negative karma fairly quickly from this method. As you back out of the terminal click/select it as many times as you can before it completely closes back up. You get negative karma for each click as it retracts, enabling you to get aroun 20-30 Karma reduction each hack attempt, depending on how quick your fingers are.
