Greetings, Vault-Dweller!

This guide was written in hopeful aspiration of aiding people (myself included) to completion of every quest in Fallout 3!

There are 3 basic categories: Side Quests, Unmarked Quests, and Repeatable Quests.

Side Quests are quests that are achievement-based (if the Steam version had achievements) and are noted in the Quest section of the Pip-Boy.

Unmarked Quests are quests that aren't progressively marked within the Pip-Boy, but you may find note(s) relating to them in your Pip-Boy.

Repeatable Quests are exactly what they sound like. Endless fetch-quests that are primarily centered around making money. Some of these have "goals" but a lot of them are just endless pits.
