vulnerability to fire and freezing that depends from how much zombies are decayed

[MrTrololo]

probably sounds like any RPG thing but it's not on my mind.

i know that low temperature can already slow down zeds but that should depend from how their state of putrification;

old,slower,weaker,dehydrated and more decayed zeds would be less affected by freezing but fire would take them out faster

fresh,faster,stronger,and not dehydrated would be more affected by low temperature but in return fire would take them down slower

additionaly during below zero temperatures(celcius degrees) zombies(at least some of them)should be able to completely freeze and be unable do do anything(especially i mean here zeds that stays idle for enough long, also ones who are sitting on ground back to wall)

,lower temperature-more severe it would be for them,obviously also for us
