The character releases warm vapor into cold temperatures

[Unamelable]

I told it like it is, what else is there to add?)

For starters It'd be better to title your suggestion "You can see your character's breath in the cold" because the current title sounds confusing.

 

Next what conditions do you see you breath? Cold weather or cold AND humid weather because I heard you need both to see it.

 

Do you see your breath more rapidly when your character is exhausted? Do you see your breath at all if you're wearing something like a mask?

 

Do different levels of cold and humid weather affect how visible your breath is?

 

Can seeing your breath be a good indicator that you need to dress warm? Right now the watch thermometer is a good indicator but if you don't have that this could be a default indicator.

 

Can your breath make you stand out more to hostile survivors or even zombies? Like imagine hiding behind cover but your breath gives you away. On the flip side it could give enemies away too including those hiding behind trees including zombies!

 

It helps to list potential applications for your suggestion(s) as well as detailed implementation.

 

But yeah that's a pretty cool suggestion that I completely missed to suggest.
