An active volcanic reef provides abundant geothermal energy but regular lava eruptions threaten your colony's eastern expansion zones.
Key Challenge
Eruption events destroy all structures in a randomly determined blast radius. The blast zones shift each eruption. Buildings in safe zones one eruption may be in the blast zone the next.
Strategy
- 1.
Build all critical infrastructure (Food Storage, Water Tanks, Residential areas) in the western zone — eruptions always originate from the east. The western zone has never been affected in any known eruption pattern.
- 2.
Geothermal Vents (unique to this scenario) provide free unlimited Fuel as long as you build Geothermal Collectors adjacent to them. This eliminates the Fuel bottleneck entirely — use this to run Distillation Towers and Generators from Day 1.
- 3.
After each eruption, new lava-cooled land formations appear in the east. These provide solid Pile Foundation anchor points and often contain rare mineral deposits. Send Sailors immediately after each eruption to survey new land before the next event.
Quick Tips
- ▶ Modular building is optimal for this scenario — design buildings that can be quickly deconstructed and moved when blast zones shift.
- ▶ The volcano's eruption warning gives 5 in-game minutes of notice. Use this window to deconstruct any structures in the predicted blast zone and relocate materials.
- ▶ Obsidian (lava-cooled material) is gatherable after eruptions and acts as a stronger version of concrete — available only in this scenario.
