Still brutal, but I like it.

I agree with Hidersine.  It should more properly say "Attempting to refuse is acting under fire."  If they blow the roll they have to acquiesce.

I'm not totally sure where there's a problem.  If you wanted to extrapolate, you could call "a guy or two" (or five) like a micro-small gang, then go to small (15), medium (30), large (60-100), and go one "size" up for each doubling or thereabouts; 150, 300, 600, 1200, 2500, 5000, 10k, 20k, 40k...  A fighting force of 5000 with assault rifles would do 1-harm to a force of 10k with 1-armor (3, minus 1 for armor, minus 1 for size), while the 10,000 guys would do 3 (3 minus 1 plus 1).

I can still pull off 3-harm with something like a shotgun, yeah?  So if it's me with my shotgun and 1-armor against an unarmed, medium mob who also have 1-armor, I'm suffering 2-harm from their punches (1 plus 2 for size difference minus 1 for armor), and they're taking 0-harm from my shotgun (3 minus 2 for size difference minus 1 for armor).  You're in trouble against a mob any way you slice it.

One interesting possibility builds on Chris's idea a bit -- have the apocalypse happening during World War II, so tech stalled in the 1940s, before assault rifles even existed.  Since AW starts 50+ years after, that means that you're now in an alternate reality present!

A couple of wicked ideas there might be that Hitler was doing some gnarly experiments (which I think he was), and pulled out something from hell or whatever, and the spirits and demons and crap are both the maelstrom and the cause of the apocalypse.

Hot.  I agree wholeheartedly.

@Bret:  I really hope I didn't come off cross.  If you don't buy it, you don't buy it, and that's cool.  Nothing says this all has to mean the same thing to all of us.  But if you'll indulge me, here's the basis for my argument:

The Angel's healing moves are what he does, you know?  He picks up his angel kit and goes out bravely into the world to patch up those with the misfortune to have their guts aspilled.

His sex move, however, I think is who he is.  He cares about people, and lives; he has to, or he wouldn't do what he does.  His Hx goes to +3 with whoever he sleeps with because he genuinely cares about his partner; he doesn't have to like him/her, but he cares enough to really understand this person.  Maybe it turns out he finds something he didn't like, and he knows to stay away; still, Hx+3 means he's in better shape to do so.

The driver drives cars, and is fast, and is awesome at it.  Why?  Because he doesn't want to be tied down.  His sex move is disadvantageous for him because despite his burning desire to not be tied down, he's been captured and made vulnerable by his partner.  It's great in the moment but there's something in it that grates against his tendencies.

Anybody can take a no shit driver or healing touch, but they flesh out what the character does, not who he/she is.  Changing sex moves, since they reflect the character's fundamental philosophy, essentially rewrites his entire outlook top to bottom.
