Do you live and breathe everything Master Chief? Maybe you were simply late to the party and wonder what happened before ‘Halo 3’? Either way, the ‘Halo Encyclopedia’, out on 2 November, is just what you’ve been waiting for.

Published by Dorling Kindersley, the encyclopedia is a mine of information covering everything from the origins of the Human- Covenant War to the size of Master Chief’s feet. OK, maybe it’s not quite that meticulous, but it is an interesting, informative read full of stunning illustrations and diagrams sure to satisfy any ‘Halo’ aficionado, although rookies may find such an exhaustive look at a virtual world a little difficult to understand. Fools.
