It comes as a surprise to absolutely no one that Subnautica 2 has finally surpassed 5 million copies sold. It did sell two million copies in just 12 hours after all. Then, not that long ago, it broke 4 million copies sold, which was excellent for everyone involved except for Krafton. And now its 5 million copies sold coincides with its first major update in early access, 1.1.
The biggest addition from the latest update was the introduction of just a little violence, after masses of players complained about the game's forced pacifism. You still can't kill sea creatures though, only bonk them on the head or zap them when they get uncomfortably close.
