While I have seen several other YouTubers survive 100 days in Subnautica, I wanted to see if I would be able to do all of that with one life.

Apart from only having one life, hardcore Subnautica also presents the added pressure of having no manual save button, meaning you can't just reload to a previous save if one of your vehicles gets destroyed or glitched out.

This was also recorded before the recent Subnautica 2.0 update, which added the unstuck button, so getting trapped or clipped into terrain is still a very real threat.

This took me an incredibly long time to make, so if you would maybe consider subscribing, it would be greatly appreciated.
