sometimes when you are driving you drillship you can find a super heated cave.Ib that cave the temperatures are so big you cant leave you ship wipout taking damage in order to safafly explore them you will need somethink like a hazmat suit but for heat instead when outside in the cave the suit will be in state of constand detirioriation and will break after some time.In these cave rich vines on miners will spawn giving you more ores meybe also some exclosive material.
I like it!
yep, suits are already planned, check the roadmap
