The fourth entry in the Reverse Design series, this book examines the way that Half-Life revolutionized the design of the first person shooter--and videogame design in general. With more than 52,000 words and almost 500 pictures, maps and diagrams, this book explains the revolution in the development of shooter cover as well as the development of the set piece style of design. This book also has unique bonus content not available in the web version, including a discussion of Half-Life's impact on multiplayer design.
