Biome expeditions
Purple Vents Sweep
A Purple Vents sweep combines useful seabed materials and wreck exploration in one repeatable expedition.
WHERE & HOW TO FARM
Purple Vents Sweep
Purple Vents seabed and surrounding thermal features, approached from the Twisty Bridges side.
Before you go
- Seaglide or Seatruck for travel.
- Depth preparation suited to the section you plan to explore.
- Scanner and open inventory space.
- A return plan that accounts for oxygen and vehicle safety.
Farming steps
- Approach the biome from the Twisty Bridges side and orient yourself using the thermal towers.
- Descend along the seabed rather than making a long open-water search.
- Collect loose Lithium, Copper, and Titanium you encounter.
- Break Shale Outcrops and gather whichever minerals they yield.
- Check nearby wreck sections for scannable fragments while keeping the seabed as your main sweep route.
- Use towers as landmarks to maintain a return direction and avoid unnecessary detours.
- Return to the Seatruck before oxygen or storage becomes a problem, then unload and plan another pass.
- Watch for Chelicerate patrols and keep a clear route back to the vehicle.
- Avoid parking or lingering close enough to a vent for heat to damage the Seatruck.
Repeat, collect and use
The route is repeatable, but individual loose resources and outcrops are collected once. Expand to another seabed section if a familiar pass is depleted.
Common mistakes
- Descending beyond the vehicle’s depth rating: verify the installed module before exploring lower areas.
- Treating Shale as a guaranteed source of one mineral: its drops vary.
- Following wreck fragments until the return is uncertain: keep the towers and vehicle in your route plan.
When to stop or switch
Finish the pass when storage or oxygen is low, or when the vehicle takes damage; switch to a focused return after upgrading depth access or repairing.
