Is Subnautica 2 Single-Player?
Yes. Steam lists Single-player as a feature, and the official description says the game is crafted as a single-player experience that you can optionally play in online co-op.
Expanded answer
Subnautica 2 is not co-op only. The official description says it is being crafted as a single-player experience that you can optionally play with up to three friends online.
That means solo players do not need to treat multiplayer as the default or mandatory way to experience the game.
This is one of the most useful pages for capturing buyers who like the series but do not want a forced co-op survival game.
