Here’s the thing tho
The turned are already cold. They are basically dead and don’t produce heat. So they most likely won’t go look for warmth. But the idea of them gaining strength at the cost of speed is a very good idea
I like the idea of slowing down the pace of gameplay in winter and wintry areas, but I’m not 100% sure about making the turned into slow moving bullet sponges.
Only if I can give them jet packs and suicide vests, to create heat seeking missles.
I was more leaning towards making it a viable option to flee, or to use your environment around you to kill the Turned, for instance, leading the Turned to ice, then shattering it, making them fall in.
The Turned do not have to behave like the most generic science fiction & fantasy type of zombie. The lore that is given on them allows Nelson far more freedom in how gameplay should work than reanimated corpses, (or fungi, viri, or bacteria as AR suggested) would.
No, they don’t that’s what makes them cold blooded.
Just because they are cold-blooded doesn’t mean they prefer cold. These animals seek heat to be active, because in cold environments, they don’t move as much. They become sluggish in cold areas but much more active in warm environments which is why you mostly see cold blooded animals in humid and warm areas instead of snowy and cold environments.
The question is: are Unturned zombies really reanimated dead corpses, or they are just (like their name says) Turned people - alive, but just mutated?
If they are really true undeads: do their blood is even flowing in their veins (not only because of heart beating/not beating, but also if their blood is still liquid or it turned solid [coagulation])?
SPOILEEEEER!!!
Summary
According to game’s lore, people are turned because of alien virus (Washington north deadzone, notes in abandoned houses).
