Subnautica

[MC Prussian]

It's fantastic. One of the best open-world games out there right now. Terrifying and relaxing, engrossing and enthralling. Underwater exploration at its finest.

 

Go and get it.

I've seen this has become popular, but not seen much of it yet. 

Is it on XB1?

[MC Prussian]

PC and XBOX only.

 

Very demanding insofar as you're stranded on an alien world covered with water and with little info what to do next. All you can do is explore the nearby surroundings.

 

But it's such a pretty game, very atmospheric. It'll also make you sh*t your pants at times due to the sea monsters around.

You can lose yourself diving in the ocean for hours and not get tired, there's always something new to strife for in the quest to get off the planet.
