Karma

From Fallout - Wiki on Neoseeker

The Karma system is a reflection of all the good or bad choices you make through-out Fallout 3. Having good or bad karma can get you bonuses from certain members of the wasteland. However there is a downside, having good karma will result in Talon Company Mercs hunting you down and having bad karma will result in Regulators hunting you down. Having neutral karma will result in less bonuses but you won't have to worry about Regulators or Talon Company Mercs.

Karma Levels

+750 to +1000 = Very Good
+250 to +749 = Good
-249 to +249 = Neutral
-749 to -250 = Evil
-1000 to -750 = Very Evil
