Fallout: New Vegas Official Game Guide

The Fallout: New Vegas Prima Official Game Guide is a publication by Prima Games. It contains strategies, maps, and walk-throughs that a player may find useful while playing Fallout: New Vegas, as well as some additional background information about the setting and characters.

Overview
Its main author is David S.J. Hodgson, who also authored the Fallout 3 Official Game Guide. The hardcover collector's edition includes 32 more pages which include concept art and background information from the developers at Obsidian Entertainment.

Additional sections

 * Tour of the Mojave Wasteland
 * Faction profiles
 * Behind the Bright Lights & Big City, additional faction profiles

Weapons

 * The guide says that the unique hunting shotgun, Dinner Bell is located at the old nuclear test site. It is actually given as a reward by Red Lucy in the Thorn, after completing the quest Bleed Me Dry.
 * The Action Point description states that firing a pistol costs 10 AP, switching between standing and crouching costs 10 AP, firing a rifle takes 25 AP, and firing a Big Gun takes 75 AP. The section is an excerpt from Fallout 3 Official Game Guide regarding AP which was also incorrect.

 * The third assassination attempt during You'll Know It When It Happens by the disguised engineer with the knife, is not mentioned.
