Hardcore Survival TTRPGs?

[2]

I'm looking for a system that would be good for a campaign centered around surviving in difficult places like dense jungles, arid deserts and frozen mountains. I'm looking for heavy resource management, harsh penalties for starvation, dehydration, lack of shelter, disease, all that. My group is definitely interested and I think it would be tough to find a system that's TOO granular for us. Thanks in advance!

The only thing that comes to my mind is Medieval Dynasty. I've heard more than once that you can literally die from anything there.
