🗺️Layout & Navigation

The Coral Gardens sit just beyond the shallows and wrap around the Welcome Center route. The dense coral towers make it easy to get turned around — keep the surface glow visible and follow the current to return. Copper clusters cling to overhangs in big patches, so one find usually means a full inventory of ore.

⛏️Resources & Farming

This is your main copper source in early access. Quartz outcroppings line the sandy floor between coral towers, and Salt deposits sit in shallow pockets. Coral Mash — used in early base modules — scrapes off the glowing coral with a knife. Nothing here is dangerous enough to need a weapon, but a Repair Tool and spare O2 tank help on long collection runs.

⚠️Dangers

The main risk is getting lost, not getting attacked. Bloom Canker colonies and small Needle Eels patrol the fringes; both are easily out-swum. Save your beacons for the cave mouths — the coral canopy hides entrances well.

What to bring

Standard loadout for a first pass: full O2 stack (Standard Air Tank at minimum, Portable Oxygen Generator for cave work), charged Scanner, Survival Tool, food and water for the swim, and at least one decoy if the threat rating is High or above. Drop a beacon at the entrance — the alien ocean has no compass zones, and landmarks plus beacons are the only reliable way back. If you have the Tadpole, take it: speed, cargo and a movable O2 refuge in one.

Route planning notes

Use landmarks, not coordinates, and press R3 on the map screen to check the Abyss layer — floating fast-travel points let you dive straight down toward ground-level destinations instead of swimming the whole way. Split any long trip into a scan run and a materials run; mixing them is how inventories get lost. Leviathans patrol the deep transition zones here, so learn the silhouette tells and plan your surface intervals where cover is available. Night can open safe windows: some predators patrol further out after dark, which trades visibility for room.

FAQ

Is Coral Gardens safe for new players?

Check the threat notes in the sections above: Low-rated shallows areas are fine from the first hour, while anything flagged High or needing an Adaptation should wait until you have the Tadpole, an upgraded air supply, and decoys. The Biomes index lists every region in rough difficulty order.

What should I build near Coral Gardens?

A forward base or at least a beacon chain if you farm here regularly. Power it with the cheapest stable source available (a bioreactor fed by fish and organics works anywhere), and keep a charged Repair Tool on hand — the same one that maintains your lifepod maintains base modules.

Where do I find copper?

Copper clusters cling to coral overhangs in large patches — one area usually has enough for a full inventory.

Is the Coral Gardens dangerous?

Low-Medium threat. Bloom Canker and Needle Eels patrol the fringes but are easily out-swum; the real danger is getting lost in the coral towers.
