Instead of killing a Zombie fig outright after a fight with it, what if you did a body damage system like this:
Roll 1d6 after a sucessfull wound,
1-4: Limb is sht/hacked/blown off, remove a leg or arm.
Zombie is eliminated.
*After three sucessful limbs have been removed, the Zombie can be consittered immobile/incapacitated. Any minifig approaching an incapacitated Zombie automatically kills it (coup de graz to the head baby!
Sound okay? Or too complicated/simple?
