Subnautica 2 Beginner Guides: Silver Map, Keycodes, and Base Building

A collection of beginner guides for Subnautica 2 covering silver map locations, eating mechanics, base building tips, keycodes, and active redemption codes to help new players survive the early game.

I also know how rough those first few hours can be — especially coming from the first game, where everything worked differently. I found myself constantly running out of oxygen, starving because I couldn't digest anything, and wandering aimlessly without a map.

So I put together a few guides to help new players get through the early game pain points:

🗺️ Silver Locations Map — Marked cave systems where sandstone outcrops spawn
🍽️ How to Eat & Not Die — Angel Comb location (158m NE of Lifepod), oxygen tricks, crafting order
🏠 Base Building Guide — Why your base floods, best locations, power management
🔑 All Keycodes — Tadpole Pens door code, locked containers, etc.
🎁 Active Redemption Codes — Bilibili Seamoth decoration, etc.

Hope these help someone. You can find them at the good game guides, ggguides.uk. The game is only going to get better from here. 🫡
