What this layer is
The Geothermal Vents are defined by extreme heat and Magma. Pools of molten rock and Lava Geysers make route planning a matter of temperature management, not just navigation. Even brief exposure can push core temperature toward heatstroke.
Laser Drones, Cryo Drones, Sawblades, Pistons, Ceiling Turrets, Coldpuffs and Spicevines add mechanical and biological threats. The layer is not in the demo; the details are pre-release and may change before launch.
