Synopsis: The Guild of the Tank

Eleanor Franks survived not one, but two apocalypses within five years of each other, only to die in a abandoned house surrounded by the undead.

...Or so she thought. Salvation comes in the form of the Rave, a large super-tank that survived the wars against the undead, and her three man crew of survivors, a band of mercenaries calling themselves the Brotherhood of the Tank. Taking her on until they reach civilization,

Of course, a super-tank is hard to handle with just 3 guys and a rudimentary AI...there's always room for one more in the Brotherhood...

...even if it is a girl that makes it so they have to change the name.
