I don't know what I expected when I bought Subnautica, but I thought it looks pretty neat and with 23€, you cant do anything wrong...
Then I started playing, and after the first minutes of swimming and exploring I completely fell in love...
The world of Subnautica is so vast and beautiful and hides a great number of surprises and challenges!
The base-building feature is very well done, the way Subnautica lets you use your crafted buildings and tools and last but not least your submarines is fantastic!
All the textwork integrated is not only informative and part of the story, but really gets you further in the story. You just CAN'T finish it, without reading many of the PDA-entries.

I finished only today and had only one bug! That, maybe is the most important fact, most of AAA-Title-Producers can't manage that.

I really recommend that game to everyone who loves the Ocean, and wants to keep up to the Challenges of Subnautica, because as beautiful it is close to the surface, as hard it gets with the darkness awaiting you!
