Subnautica (Series) Review

Posted: 21 months ago, last updated 4 days ago.

Author: @GeekDadGamer, Jo Robertson and Rich Adams.


Subnautica is an open-world adventure where you explore the ocean on an alien planet after crashlanding. You collect resources and fight creatures to survive. This enables you to establish an underwater base, gain new craft and equipment and explore deeper into the sea. As you do things get eerie and the game reveals itself to have thrilling horror elements.

Your main objective is to explore the ocean and survive its dangers, while also completing tasks to advance the plot. You collect resources, craft tools, bases, and even submersibles. The largest part of the game is underwater although there are two islands to explore.

You can play in different modes:
  • Survival: Dealing with depleting health, hunger, thirst and oxygen. You can respawn if you die but lose items.
  • Freedom: Hunger and thirst disabled but otherwise like Survival.
  • Hardcore: If you die you have to restart from the beginning.
  • Creative: Health and thirst are disabled. You also have access to all crafting without the need for resources.
  • VR: The game can be played in VR mode with headsets such as the HTC Vive and the Oculus Rift, with the additional input of a keyboard and mouse or game controller.

It creates an experience that invites you to dive into an underwater ocean. There’s an open and immersive watery world to discover. Construction is predictably challenging, with air pressure and resources a battle to keep balanced. These housekeeping concerns are as occupying as the daunting, enigmatic and mysterious depths of Subnautica’s world. Although set in the future, Subnautica draws back a curtain on the real underwater worlds we know but can’t explore in a prolonged way.

Age RatingsAge Ratings

Content Rating

This game was rated PEGI 7 for frequent mild violence and scenes which younger children may find disturbing. Violence is very mild and is viewed entirely in the first person. Fend off alien creatures with your survival knife. Although some of the aliens bleed a little, injuries are not visible. Some locations can be dark and combined with the strange creatures, may be scary to younger children.

In addition to the rating parents should note that at one point players add bleach to water to make it drinkable in the game.

10-16 year-olds usually have the required skill to enjoy this game.


You can select Survival, Freedom, Hardcore or Creative modes that offer different difficulties. The game uses small icons for menus and to identify items, but when you select them a black box pops up with white text to describe what they are.
