The graphic, the environment, the sea creatures, the ambience all are great and super cool. You will awestruck by the sea beauty and you won't believe your eyes when the night come it is multiple times more beautiful. I personally will give 10/10 for this survival games. The story lines make sense and the most important part is when you're playing Subnautica you will feel that you immerse into the game. SUPERB SUBNAUTICA 10/10
