(Don’t) PANIC!!!
If there's one book the creators of Warhammer haven't drawn inspiration from, it's the Hitchhikers Guide to the Galaxy. On its cover are the words "Don't Panic" in large, friendly letters. But any Warhammer unit (well, except for those nasty immune to psychology guys) can, and most likely will, panic and flee. Join GJ on a journey from 1st edition Morale tests, to Oldhammer era Cool tests, to the panic tests we all know and dread. So don't panic. But if you do, prepare to be pursued.
