Might I make a suggestion?
No stresses...zombies shouldn't feel stress.
Just consequences...simulating things getting blown off. All zombies take all consequences possible. The drive to feed is too strong.
This allows players to tag consequences faster killing zombies faster. It also creates vivid imagery of limbs flying, zombies blown in half crawling forward (extreme consequence owned by a chainsaw...etc.)
The downside is instead of only having to deal 11 to blow a zombies head off...you need to do 18.
So I suppose I invalidated my suggestion....
Ah well, I like the idea all the same.
I was actually thinking of changing it to give them
no Endurance skill, so they've only got the base two stress boxes. Given that the PCs will either come with weapons or fashion weapons of some kind in short order, it's not that far off from having no stress boxes.
Though maybe 'fresher' zombies might have a point in Endurance, a stunt like No Pain, No Gain or Tough Stuff, or even a Fair Athletics score to make them a bit hardier and tougher to put down. On the flip side, more decayed zombies might have deteriorated Might or Fists scores, and maybe come with some consequences already taken.
As for headshots, I'm dithering on how to actually work that. Maybe make them have to tag a maneuver, or spend a fate point if they're in a hurry to invoke their "Removing the Head or Destroying the Brain" aspect. Or maybe make it happen whenever they roll a natural +4.
Or both, to allow for people to either aim (spend an action navel gazing, but not attacking first), take advantage of a Moderate or higher consequence (cripple it to stop it from moving, the head's an easier target to bash in), or just plain getting a lucky shot (either the rare +4 on the roll, or spending a fate point to make the luck happen). In any case, I don't want it to be something as easy as making a free-action declaration and tagging that.
How's this look:
Romero Style ZombieHigh Concept: Shambling Flesh Eating Corpse
Other Aspects: Driven By Hunger; "Removing the Head or Destroying the Brain"; Slow but Steady; Just One Part of the Shambling Horde

Great (+4): Might
Good (+3): Fists
Fair (+2): Alertness,
Average (+1): Athletics
Stunts:
Powers:
Living Dead [-1]
Claws [-3] (Venomous, biting)
Total Refresh Cost:
-4
Stress:
Mental OO
Physical OO
Social OO
Notes: The classic shambling zombie is slow to move, and on the surface looks fragile, but as a being driven solely by hunger, simple things like wounds and lost limbs aren't going to make it stop, so they should take every consequence before being Taken Out--and should get back up again anyway unless someone puts a bullet through its brain. While one zombie may seem easy to deal with, they've got a Weapon:2 venomous bite, Great (+4) death grip (har har) for grappling, and where there's one zombie, there's almost always more--especially since any characters Taken Out by a zombie bite will rise soon after to join their ranks. Use the time it takes them to shamble into range to put them down, or at least blow enough bits off them to make good your escape.
<Billy> The stat block represents the 'average' zombie. A fresher, meatier zombie might have a Fair (+2) Athletics score, Average (+1) Endurance, and one or both of No Pain, No Gain and Tough Stuff, making them tougher to put down for the count. Likewise, a more decayed zombie's stats might be a point or two lower all around, and may have already taken consequences.
<Harry> What, no "Braaaaaaains" aspect?
