Choose Your Own Adventure #70.

It goes without saying that robots kill. They hunt, swarm, and fire lasers from their eyes. They even beat humans at chess. So who better to stand with us when the real villains arrive? Movies instruct us that, whether we like it or not, we will one day be under siege by pirates, ninjas, zombies, aliens, and Godzilla. Also great white sharks. And-let's face it-we're not prepared. But with the advice contained in this brilliantly illustrated, ingenious book, you can build your own robot army to fend off hordes of bloodthirsty foes. From common-sense injunctions ("never approach an unfamiliar robot in a militarized zone") to tactical pointers ("low-power radar beats cameras for detecting mummies in a fog-shrouded crypt") to engineering advice ("passive-dynamic exoskeleton suits will increase sprint speeds but not leg strength"), this book contains all the wisdom you'll need to fend off the coming apocalypse. Witty, informative, and utterly original, How to Build a Robot Army is the ideal book for readers of any age.

An extremely imaginative and lyrical Invasion Manual of Earth - not for Aliens, but for Demons. Encyclopaedia of Hell has been hailed by critics such as Fred Durst, Penn and Teller and Lars Ulrich as one of the funniest books ever written.

"No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's..." So begins H. G. Wells' classic novel in which Martian lifeforms take over planet Earth. As the Martians emerge, they construct giant killing machines - armed with heatrays - that are impervious to attack. Advancing upon London they destroy everything in their path. Everything, except the few humans they collect in metal traps. Victorian England is a place in which the steam engine is state-of-the-art technology and powered flight is just a dream. Mankind is helpless against the killing machines from Mars, and soon the survivors are left living in a new stone age. Includes the original Warwick Goble illustrations.

From killer toads, feral felines, and brown tree snakes to multiple invaders in the Great Lakes and Lake Victoria, Alien Invaders explores the impact on our ecosystems of the wave after wave of invaders and why they have become a worldwide concern. Environmentalists Jane Drake and Ann Love take us on a journey from the days of sailing ships and shipboard rats to the fungus that sparked the Irish potato famine to the beautiful but deadly purple loosestrife strangling native wetlands, while presenting the concepts of biodiversity and endangered species. Learn where the invaders originate, how they travel, what they displace, why the invaded natural system is vulnerable, and what can be done. Discover if you are an invader or a saver and how you can help.
