Incredible Half Life Secrets That You Probably Don’t Know

Half Life 2 Raising the Bar had many interesting concepts

In case you were unaware Half Life 2 Raising the Bar is a coffee table book written by David Hodgson and published by Prima Games in November 2004, in a hardback and paperback cover. The book is really interesting because it has concept drawings of different enemy types, character development, cut concepts, information relating to voice actors and game development. The book really helps you go into the mind of the developer and what they were thinking at the time of development. The book now is a collectible item and is quite rare.
