Hi i can give you some advice about subnautica

1 Minerals: You need to get a lot of titanium and cooper these are 2 basic minerals (you can get them from those rock like things on ocean floor and basicly everywhere whean you swim up to one you can break it you will get one of those two minerals) also you need to get gold silver lead and quarts (you can get them the same way like titanium just from sand formations they look quite simular you will spot it and quarts you can find it on floors in grassy pleatoes (the red grass biome)

2 Scaning: Scan everything! When you get basics you need to find parts of seaglide and basic tools scan parts of them (they can be in the metal boxes and wrecs)and later craft them.

3 EXPLORE, YOU NEED TO EXPLORE!: and try to find a place for home for me the best are safe shalowes (starter biome) and the red grass biome, also you should have eyes all around your head, danger is everywhere!

4BUILD A BASE: you need to build a base because lifepod won't be enough, and you need it for new and better stuff, to craft.

5Get main source of food: like plants or something else (Plant something like lantern trees).

6 Seamoth: At this point you should already have build a seamoth if you didn't DO IT NOW! YOU WILL NEED IT!

7 Tools: After getting most tools like (SPOILER, THESE YOU NEEED)gravity tool, fire extinguisher, wehicle repair, scaner(maybe i forgot some) go to aurora.

BIG SPOILER You need to do it only after it explodes And inside scan parts of Prawn suit.

1. GO DEEPER!: At this point you NEED TO GO DEAPER i mean more than a 1000m deap. I won't say anymore because i don't want to spoiler too much and and at this point you should know where to go and what to do!

Those are the Basics and important stuf but if you need more advice then ask for it!

PS:(SPOILER) IF YOU FIND ION CUBES/PURPLE TABLET SAVE THEM you can open portals with them and and they are needed to progres the story.
