This is my first time beating Subnautica, but it was a fun 30-hour long journey. Surviving 100 days in Subnautica, I completed the main story, built a base, maxed out all Subnautica achievements, upgraded all the tools and vehicles and engaged into some life-threatening encounters.
The biggest challenge with this survival was probably fighting off a ghost leviathan that got me cornered in a cave, but I really wanted to get outta there and also save my cyclops, so I had to learn some tricks to free myself.
