I’ve been glued to Subnautica 2 for the past three weeks, and I’ll admit my first run was a total mess. I spawned, grabbed the first scrap metal I saw, and got chomped by a shadow leviathan 12 minutes in because I ignored the AI companion’s warnings. That’s why I put together this guide for anyone starting their Subnautica 2 AI first playthrough, to help you skip the frustrating mistakes I made and actually enjoy the weird, beautiful alien ocean right off the bat.
What the Subnautica 2 AI First Companion Actually Does (And What It Won’t)
The in-game AI isn’t just a generic tutorial pop-up that vanishes after 10 minutes. It’s a dynamic companion tied directly to your escape pod’s core systems, and it learns alongside you as you explore new biomes, scan creatures, and collect resources. It will track your oxygen levels, ping nearby harvestable materials, and warn you of incoming threats, but it won’t hold your hand through every part of the game.
For example, if you wander into a biome it hasn’t fully scanned yet, it will only give you vague warnings instead of exact threat locations. I learned this the hard way when I wandered into the bioluminescent kelp forest and it just said “unidentified large life form detected” 2 seconds before a stalker bit my air tank clean off. The AI companion’s scan range only extends 75 meters from your current location by default, so don’t assume you’re safe just because it isn’t pinging threats right now. You still need to keep your eyes peeled for hidden dangers, especially in shallow, rocky areas where predators like to hide.
4 Priority Tasks to Complete in Your First 30 Minutes
It’s really tempting to rush off and explore the nearest deep crevice as soon as you spawn, but taking 30 minutes to knock out these simple tasks will save you hours of frustration later on. For anyone doing a Subnautica 2 AI first run, these tasks are non-negotiable if you want to avoid dying every 15 minutes.
- Sync your AI companion to your handheld scanner first. This lets it log resources you scan even when you’re away from the pod, so you don’t have to backtrack constantly to look for copper or titanium when you need to craft new gear.
- Collect 12 titanium, 6 copper ore, and 3 silicone rubber before you go deeper than 50 meters. These are the base materials you need to build a better oxygen tank, flippers, and a portable storage unit that will make longer runs way easier.
- Scan at least 3 small local life forms in your starting cove. The AI uses these scans to calibrate its threat detection system, so it can tell the difference between harmless herbivores and aggressive predators much faster.
- Mark your escape pod’s location with three floating beacons. It’s really easy to get turned around when you’re chasing a rare resource, and the AI’s navigation tool is notoriously glitchy when you’re more than 200 meters from the pod.
I skipped the creature scanning step on my first run, and the AI kept pinging every small silver fish as a potential threat for almost two hours, which was so distracting I missed half the resource deposits right in front of me. You don’t need to fight any predators in your first hour of play – the starting cove has all the resources you need to gear up, so there’s no reason to pick fights you can’t win yet.
Common AI First Playthrough Mistakes to Avoid
I made almost all of these mistakes on my first two runs, so I can speak from experience when I say they will ruin your early game fun if you’re not careful. First, don’t turn off the AI’s warning notifications to reduce screen clutter. I did that on my second run, and I didn’t notice my oxygen was running low until I was 120 meters deep, with no way to get back up in time. The AI’s low oxygen and threat warnings are customizable, but never turn them off entirely – you can adjust their size or position in the settings menu instead if they get in your way.
Another mistake is ignoring the AI’s resource location pings because you think you know where to find better materials. The starting cove might not have diamonds or lithium, but the AI only pings resources you actually need for your current crafting queue, so if it’s pointing you to a titanium deposit, that means you’re short on titanium for that tool you’re trying to make. It saves you from having to open your crafting menu every 2 minutes to check what you’re missing.
Also, don’t assume the AI’s threat assessment is 100% accurate. It doesn’t recognize camouflaged predators until they’re within 20 meters, so you still need to keep an eye on your surroundings when you’re exploring new biomes. Camouflaged sand sharks are responsible for 40% of early game player deaths, according to recent community stats, so don’t rely solely on the AI to warn you about them. If you’re swimming over a sandy area, move slow and watch for moving patches of sand.
How to Unlock Advanced AI Features Early
You don’t have to wait 10 hours of playtime to get access to better AI tools. There’s a secret data terminal 85 meters deep in the starting cove’s western crevice, hidden behind a small rock formation. If you scan that terminal within your first two hours of play, you unlock the AI’s extended scan range and resource prediction tool, which tells you where rare resources are likely to spawn before you even scan them. I found this by accident on my third run, and it cut my early game grind time in half.
You only need a standard oxygen tank to reach this terminal – you don’t need a rebreather or any special gear, as long as you don’t stop to look at anything on the way down. The crevice doesn’t have any aggressive predators, so you don’t have to worry about getting attacked while you’re down there. Just make sure you leave enough oxygen to swim back up to the surface.
Also, if you scan three abandoned data pads scattered around the starting cove, you unlock the AI’s creature taming guide, which lets you feed small herbivores to get them to lead you to hidden resource caches. That’s a game changer if you hate searching for rare materials like silver ore, which is usually hidden in small nooks you’d never find on your own. I once got a small glowing fish to lead me to a cache with 8 silver ore and 2 gold nuggets, which let me build a better scanner 3 hours earlier than I normally would.
At the end of the day, your Subnautica 2 AI first playthrough is supposed to be fun, not a stressful grind. Take the time to learn how the AI works, prioritize your early tasks, and don’t be afraid to slow down and explore the little details of the alien ocean. You’ll still die a few times, that’s part of the fun, but these tips will help you avoid the most frustrating early game mistakes so you can focus on the parts of the game that matter most.
