You can find out more by following the link to the Black Library. You can also follow them on facebook, where they are doing an online play through the book, with the readers there voting on the decisions being made. Thus far the dice are not on their side.......

The forces of Chaos are moving against the Imperium once more, and only YOU can stop them! The first in a new series of Warhammer 40,000 adventure game books, Hive of the Dead casts you in the role of an Imperial Guardsman, fighting for survival upon the plague-ridden world of Subiaco Diablo at the beginning of the Thirteenth Black Crusade. Face all the horrors of Abaddon’s legions, including Death Guard Chaos Space Marines, the walking dead, and foul warp-spawned daemons. Will you make the ultimate sacrifice for the good of mankind, or will your name be forgotten with the rest?
Enter the hive of the dead
Hive of the Dead is the first ever Warhammer 40,000 gamebook. Using rules reminiscent of those in the Warhammer 40,000 tabletop game, albeit without models and terrain, you can venture through a hive-world infested with flesh eating zombies, ghouls and worse. With only this book, a six sided dice and a pencil, you can battle the zombie hordes from the comfort of your armchair.
