Really a very nice game.
This idea of an underwater world combined with survival, a great story and possibly even a touch of horror brings this great adventure to the top single player survival games on my list.
Great sound design and also very good game mechanics.
I highly recommend it!

This game is more than just an ordinary game.
The freedom to discover and improve your skills you are able experience here is great. Thanks a lot to the developers @Psyonix and @Panic Button Games for their great commitment they put into this project all these years.
I can heartily recommend this game.
