Guide Overview
What this guide will help you do
This example guide is not about memorizing the whole map. It is about building a reliable early loop: leave, gather, return on time, stock basic materials, and establish a base that actually supports the next expedition.
Priority systems
Oxygen, water, food, and storage
Best phase
Crash landing to first functional base
Main risk
Getting lost, overfilling inventory, diving too deep at night
Recommended approach
Short-radius exploration with deliberate return paths
Stabilize short loops before you try long expeditions
The key early question is not where you can go. It is whether you can return consistently. Treat the area around your base as several safe-radius loops with one objective each.
- Loop one solves water and basic food.
- Loop two focuses on tools and oxygen upgrade materials.
- Loop three starts touching navigation-heavy terrain.
The first base should solve survival, not style
Build where returning feels cheap
An early base is valuable because it reduces travel cost, not because it has the best scenery.
Power first
Without stable power, every other module becomes temporary.
Storage second
Storage density defines how efficient your crafting loop becomes.
Expansion last
Only expand after your resource cycle stops feeling fragile.
Resource discipline matters more than fast scavenging
- Keep a reserve stack of every core material at base.
- Store common materials in fixed lockers.
- Use night dives for familiar resupply, not deep exploration.
