Planet Steam 2008

Welcome, dear Imperialists. It's the year 2415. The interplanetary federation (IPF) has done a great job in the last centuries. All necessary precautions have been taken to conquer this planet named "Steam". The core of the planet consists of a 6,500º Celsius hot source containing different resources, including water. It has taken over one hundred years to complete the first block of 42 shafts from the surface to the core.
