Three decisions to settle before May 14: which platform to buy on, how to spend your first hour, and how to keep a 4-player group from falling apart in lobby. Plus a checklist so you don't forget the boring stuff.
Where you buy or subscribe matters more than usual here. Steam and Epic are $29.99 PC purchases, while Game Pass adds no extra charge if you already subscribe. Steam, Epic, and Xbox each have different account and launcher ecosystems. PS5 and Switch are not options.
Treat hour one as a mapping run, not a speedrun. Stay near spawn, scan everything, build a tiny storage base, head back before oxygen and hunger become the story. The first death usually teaches more than the next five hours.
4-player co-op collapses fast without a plan. Pick a navigator, a base builder, and someone who watches emergency supplies before anyone leaves spawn. Share platform info now so nobody is missing a friend code on launch night.
Pre-launch planning advice based on official store/Game Pass listings, what Unknown Worlds has said publicly, and how the original Subnautica played in its EA period. Specific in-game tactics get added once we have hands-on hours in the May 14 build, not before.
