Kill All Monsters Omnibus Volume 1Hardcover, 1 August 2017

Monsters rule the world. Humanity's last hope is a squad of giant robots and their skilled pilots, all from different backgrounds, each with a unique reason to fight. Can we survive the conflict? Are we worth saving? A familiar but wholly original story about war, survival, and the human spirit, told through gigantic-scale battles fought by memorable characters! Contains over 100 pages of new story, in addition to collecting the entire hit webcomic!

Although May gives us plenty of giant monster-killing, he's smart enough to make sure that there's a reason we care that the robots are fighting the monsters rather than just saying Hey, robots fighting monsters is cool, right?

May and Copland have engaged in some pretty cool world-building, taking the basic idea and running with it until they have something special that goes way beyond what you might expect from another giant monster title. -Robot6
