The Bottom Line: Drinking Water — How to Get Water — you’re gonna need more of this than you think. I’ve lost count of how many times I’ve had to swim back to a cave because I thought ‘three is enough’ and then needed six more for the next upgrade. Mark the locations on your HUD. Set up a Scanner Station nearby. And if you find a large vein, don’t walk away — come back with the right tool. Your future self will thank you when you’re not hunting for one more piece at 2 AM.
Frequently Asked Questions
How do I get water in Subnautica 2?
Collect Water Slugs from Coral Reefs (bright neon-blue, easier to spot at night). Craft Water at Fabricator: Water Slug x1 = +40 Water. In emergencies, eat a Water Slug directly from inventory.
What happens when Water reaches 0?
Reaching 0 Water causes immediate death — unlike starvation which drains HP gradually, dehydration kills you instantly.
What is Isotonic Water?
Isotonic Water restores +55 Water (vs +40 for regular Water). Craft at Fabricator: Flash Slug x1 + Salt x1. Better for mid-to-late game expeditions.
