Fallout 3 karma achievements and trophies

 are achievements and trophies which require you to have either bad, neutral or good karma upon reaching levels 8, 14 and 20. Additional karma achievements can be unlocked at level 30 after downloading the Broken Steel DLC.

Good Karma

 * Protector (level 8)
 * Ambassador of Peace (level 14)
 * Last, Best Hope of Humanity (level 20)
 * Messiah (level 30) - requires Broken Steel DLC pack

Neutral Karma

 * Mercenary (level 8)
 * Pinnacle of Survival (level 14)
 * Paradigm of Humanity (level 20)
 * True Mortal (level 30) - requires Broken Steel DLC pack

Bad Karma

 * Reaver (level 8)
 * Harbinger of War (level 14)
 * Scourge of Humanity (level 20)
 * Devil (level 30) - requires Broken Steel DLC pack

Strategies
It is possible to get all three karma achievements/trophies for each level in a single play through of the game, by saving the game just before you gain the level (levels 7, 13, 19, and 29) or even two levels before if you use the Here and Now perk (levels 12, 18, and 28). Use one of the strategies below to change your character's alignment and level up, then reload the original save game. The achievement/trophy will stay on your account. Also, keep in mind if your karma is neutral, then any of these methods work to get you to become good or evil.


 * As an evil character, donate caps to a church (1 cap raises your karma by 1, so a max of 1250 caps is required)
 * As a good character, slaughter a town (1 murder lowers your karma by 100, so a max of 13 kills is required)
 * As a good charachter, access an unowned terminal and close it, rinse and repeat (counts as stealing, so a maximum of 250 times is required, making this method very time-consuming)
 * If you have the Broken Steel DLC, you can get the final karma rewards much easier by taking the Escalator to Heaven, Devil's Highway, or Karmic Rebalance perks to set your karma to good, evil, or neutral, respectively.
