Have you tried Subnautica Below Zero yet?

I love deep oceans and Astrology,Aliens, Structures and this game is perfect for me ive been watching a lot of vids about SubnauticaAnd Subnautica below zero.

This game looks a bit similar to subnautica, maybe i aint sure, but this game is great i can say, but not well optimized, dev should optimized the graphics and gameplay so anyone would be able to play it without any problem.

The best subnautica game the second one is okay it's also the best survival game in my opinion
