Right now, it is an arctic, less complete subnautica. Not everything is added yet, actually, there are only a couple of biomes. Nothing is really on the ice and most of the story isn't here yet. Has borrowed some things from subnautica like some fauna and if you are in creative mode, you can build the original vehicles. It is everything you would expect from an early access game. When it is complete, however, it will most likely be the most terrifying experience anybody could have from a survival game. I'd say just get it now since it is cheaper than at launch, play it for yourself, mess around and test the game. (Just note that this game is VERY incomplete. Some items don't have textures or even models. The game right now doesn't actually have a lot of new things, however there is weather, ability to name and change the color of bases.)
