I have about 250 hours in the original Subnautica and I just got around to playing BZ. I'd heard so much about how disappointing it was compared to the original so I put off playing it for a long time, but having finished it now I can say with 100% certainty it is still an amazing game. It definitely has its problems; the map is smaller so to compensate you move slower but it doesn't make the map feel bigger it just makes you feel slower. Gathering resources is still a slog. The A and B plots don't feel particularly connected. But even with that it still left me breathless in places. The environments are beautiful. The speculative biology of 4546B is still stunning. The story is emotional and driving. All in all, while it may not be as good as the original, Below Zero is still an amazing game and an awesome continuation of the Subnautica story. I really hope more people give it a chance, especially now that Subnautica 2 is releasing early access.

I mean, I had more fun with the first game, but this one was good too. I hope Subnautica 2 comes out, I'm guessing that one will be even better.

"The first Subnautica is better". Brother, Subnautica 1 is the best survival game ever, of course it is better. This is a stand-alone dlc worth every penny.

Subnautica: Below Zero is basically me saying “I’ll just explore for 5 minutes” and then suddenly it’s 3 hours later and I’m lost in the ocean with a giant creature screaming somewhere in the dark. The game looks amazing and exploring the underwater world is really relaxing… until something big decides you look like lunch. Not as scary as the first game, but still really fun and easy to get addicted to. 10/10 would panic swim back to my base again.

It's like Subnautica but slightly disappointing. A less magical version. If you can't get enough Subnautica buy it, preferably on sale. If you only played the first game once this might not be a good purchase for you.
