Hi this is my first suggestion. I think Rust should have Hot Springs. Hot springs will regenerate your HP slowly if you’re in the water. And can be a great aesthetic place where you can build your base at. You can also make Sulfur rocks more common. In the real world there is tons of Sulfur in or near Hot Springs. It will also be nice when you go too deep in the hot springs and you touch the bottom you’ll start to get hurt as there’s magma on the bottom. (Feel free to add more suggestions for the hot spring in the comments.)
A great aesthetic place where you slowly regenerate your HP in a hot Spring would be a nice chillout zone, but:
Hi thanks for your friendly criticism. I really want to talk about when your swimming over the water. The water will be pretty deep not as deep as the oceans but not like a showell kiddie pool. So you can just float over it. The second one I do agree with there will be lots of people there getting sulfur. Thanks for your feedback. :)
