Pros
Pro The sound effects really set up the overall atmosphere
The sound design in Subnautica is amazing. Even though the soundtrack can be bland at times, the sound effects for the ocean noises are incredibly atmospheric and really help to get the player in the mood for exploring a vast, alien ocean.
Pro Great theme and looks
The game takes place underwater, and with that it looks quite good for an underwater game. Looking up at the sun through the ocean looks pleasant and real. Coral reefs have multiple colors and look real as well. Graphics wise this game looks great and pulls off its theme of an underwater survival quite well.
Cons
Con Lacks Co-Op
This game was meant to be a survival game (and a bit of horror), most survival games are difficult, may get boring to play alone after time and this game has both. Having a second survivor in the story would mean to rewrite it again, but having a friend in an alien world would be better.
