The Planet Lander is the basic unit for exploration of planet surfaces, usually intended to gather minerals and biological data. The SIS can hold up to ten at a time, and they can be produced at a cost of 500 RU per unit. They typically hold twelve crew each and can carry 50 tons of cargo before returning to the ship. They are also equipped with a stun beam in order to subdue hostile lifeforms on a planet so they can be researched to gain biological data.
The planets landers can also be upgraded. Technological advances bought from the Melnorme for this include double cargo capacity, increased rate of stun beam fire, increased speed, resistance to alien life attack, heat shielding, lightning resistance, and earthquake shock protection.
