Cons: The map is only 1/3 of the size of the map from the first game, there aren't many leviathans, the Cyclops is absent, and the base swimming speed has been decreased. Pros: Extremely polished, has added tons of quality-of-life improvements, huge upgrades to base building, new biomes to explore and creatures to see (and/or eat), more land exploration (could be a con to some, it is subjective), the Seatruck is very fun to use, it adds a hoverbike for land travel, and adds lots of new gadgetry both alien and Alterra. I don't think the story was quite as good as it was in the first game but it was interesting and I liked piecing together the mystery of it all via the audio logs found in numerous places. My take: When it came out, many people went into it expecting a Subnautica sequel, but this is not Subnautica 2, this is a spinoff game for those who have already completed the first one. I think that for those who really enjoyed the first Subnautica this game is worth playing and exploring because personally I had a lot of fun on both of my playthroughs.
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.
a lot more story focused than the first game, and that in itself comes with a couple shortcomings. it is a much smaller game and it doesn’t feel like there is much emphasis on exploration compared to the first. however, i still really enjoyed this game. i thought that the story was very interesting and that the setting was quite cool. i haven’t played the first game in a while, but it still scratched that subnautica itch while i wait for the second game. also, i really, really, want to adopt a pengling.
