Subnautica: Getting Past the First Hour Without Starving

Day 1: Don't Panic

You crash-landed in an ocean. The instinct is to swim down deep and explore — resist it. Your first priority is survival basics: food, water, and oxygen. Your damaged lifepod has a Fabricator (the blue glowing machine inside) — this is your crafting station.

Getting Water

Seawater is undrinkable. You need a Bladderfish (common yellow-white fish in the Shallows) to fabricate Filtered Water. Collect 2–3 Bladderfish in your first dive and put them in the Fabricator. You can also eat them raw for minor hydration but far more food value.

Getting Food

Peepers (large bright orange fish) are the best early food source. They provide significant hunger restoration. To cook them: pick up a fish with E, place in Fabricator → Cooked Food → select fish. Raw fish is edible but less efficient.

The Kelp Forest

30–60 meters from your lifepod, northwest, lies the Kelp Forest biome — visually distinct with tall stalks. This is your first real exploration zone. You'll find Stalker Teeth on the sandy floor (needed for early blueprints) and Crash Powder fragments. Don't go deeper than 100m yet.

First Tech Priority: Seaglide

The Seaglide is a handheld propulsion device that massively increases swim speed and frees you from constantly watching air. Find its blueprint fragments in the Kelp Forest and Grassy Plateaus. Build it as soon as you have the components — it transforms exploration.

First Base Component: Habitat Builder

The Habitat Builder (Blueprint in the shallows, materials: Titanium + Wiring Kit) lets you build an Oxygen Base — a room you can extend with tubes, fill with lockers, and use as a mid-ocean storage and air point. Build your first base at 30–50 meters depth, roughly equidistant from your lifepod and the Kelp Forest.
