Subnautica is a first person survival video game. You are in a some kind of high tech raft and you are trying to survive by gathering materials and food from the ocean. It is very beautiful and has good graphics and from popular reviews it has 4.5 stars. It is available on Ps4 (free) and on pc (free) and also Xbox one and Xbox Series X and Xbox Series S for €25. It is a good game and personally one of my favourites. Unfortunately though it does not contain a multiplayer feature, but it would be extremely fun to play with your friends.
