The Kill Lock — IDW Publishing
Issue: #2
Bonded by their Kill Lock, four robots search for a cure-a way to live, and die, independently. Their only clue is a bot known as The Axial, supposed to be a creator of the Lock and keeper of its secrets. Of course, the first thing they have to do is find her... without getting themselves killed!
