Thermal Vents

Superheated volcanic seabed — a hostile environment that doubles as the best geothermal power site on the map.

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.
