Half-Life 2: Raising the Bar - A Behind the Scenes Look: Prima's Official Insider's Guide is a coffee table book written by David Hodgson and published by Prima Games in November 2004, in a hardback and paperback cover, comprising a collection of images chronicling the development of Half-Life, Team Fortress, Day of Defeat, Counter-Strike, Counter-Strike: Source and Half-Life 2. Text includes notes on game design, development, cut concepts, information relating to voice actors and game development. Numerous interviews of the Valve staff members also fill the book.

The book has been discontinued and has thus become a collectible item, although it can still be found on websites such as Amazon.com. It is also not listed anymore on the Prima Games official website.
