The Thermal Vents are stretches of volcanically active seabed venting superheated water. The heat is an environmental damage source — and simultaneously the single best energy opportunity in the game.
Power
A base built near active vents can run on geothermal power, the most reliable and high-yield energy source available. Many players establish a dedicated vent outpost purely as a power and fabrication hub for deep expeditions.
Hazards
- Heat damage to unprotected divers near active vents.
- Eruption cycles — vents are not static; timing matters when routing through.
Strategy
Pair a Thermal Vents power base with a thermal-resistant approach (vehicle + planned routing). The payoff is effectively unlimited base power for the rest of the game.
