How hosting works in Subnautica 2 co-op

Hosting pages are useful because groups want to understand the rules before they commit time, especially around saves, session control, and who needs to be online.

Quick answer

Hosting should be explained around real session friction: who controls the world, what the host is responsible for, and how the team should plan around save ownership and availability.
