Subnautica 2 Early Access Review

Rating: 7/10 (Good)

It’s pretty impressive that wading in the shallow tides of Subnautica 2's Early Access debut is as fun as it is already, and that should be a great sign of things to come, but I also wouldn’t blame anyone for waiting for these waters to rise a bit before getting their feet wet.
