Fallout 3 quests

This is the list of known Fallout 3 quests. For a detailed walkthrough, visit each quest's page. MAY CONTAIN SPOILERS. Note: Every quest that gets marked on your Pip-Boy that is completed will give you an achievement on the Xbox 360 and PC, or a Trophy on the PlayStation 3 (Because you only get achievements/tropies for main and side quests, not for unmarked quests)

Main quests
"Galaxy News Radio" can be skipped by a Speech check or by meeting Doctor Li in Rivet City directly. (If you skip this quest and talk to Three Dog to do this quest later, the reward will be a location for weapon stash.) "Scientific Pursuits" can be skipped by finding Vault 112 without meeting Doctor Li, but you will not receive the Scientific Pursuits Achievement. Another way to skip "Galaxy News Radio" is to find your father's holotapes in the Jefferson Memorial. "Rescue from Paradise" can be skipped with a Speech check, or by having the Child At Heart Perk.

Side quests

 * '''Rescue from Paradise (quest)
 * Paradise Falls
 * Release Children From Slavers

Unmarked quests
Aside from the major quests listed above, there are a number of minor ones that are not listed as quests in your Pip-Boy. They don't count as achievements either.

Repeatable quests
Some characters want specific items. These can be repeatedly given for xp, caps or Karma.

DLC quests
Quests that will appear in the downloadable content packs.
