Various Internet retail postings have suggested the existence of a book for Gears of War. This novel's complete title is Gears of War: Pendulum Wars - The Battle of Aspho Fields. Dates for availability vary depending on the country of origin, but all expect the book to release in 2008.

The subject matter of the story will be a prequel to the first Gears of War game. Readers will find out the backstory behind Marcus Fenix and the events of the Locust-Human war that were only hinted at in the game. The novel is being penned by Steven L. Kent, who was a freelance gaming journalist and author of The Ultimate History of Video Games before deciding to concentrate on novel writing.
