Plan B: Terraform – Worlds of Fire and Water

Plan B: Terraform – Worlds of Fire and Water presents two new planets to terraform. The Fire World is a volcanic planet with constant eruptions, extremely high temperatures and no minerals at the start. The Water World is almost entirely covered by oceans, with only a few islands available for early colonisation.

On the Fire World, minerals come from basalt, which forms as lava cools and can then be extracted. Players have new terraforming tools to neutralise greenhouse gases in the atmosphere and can launch solar shade satellites into orbit to reduce temperatures. Water is initially supplied only by a few small geysers, but rockets can later be launched to bring large ice comets that add liquid water to the planet.

On the Water World, players cool the planet so that the ice caps grow and the water level falls, revealing new land. Dams and terrain reshaping can also create more dry land. Water in contact with the ocean floor becomes rich in minerals, which can be extracted with filters. Mineral-polluted water prevents plants and plankton from growing, so areas must first be cleaned to allow plants to take hold. The plants help plankton spread, and the plankton neutralises nearby mineral pollution and is also essential for oxygen production.
