Though frequently found in the Ecosphere, Class N planets are not conducive to life. The terrain is barren, with surface temperatures in excess of 500° and an atmosphericpressure more than 90 times that of a Class-M world. Additionally, the atmosphere is very dense and composed of carbon dioxide; water exists only in the form of thick,vaporous clouds that shroud most of the planet.
- No Water - No Fishery or Waterport
- Thick Atmosphere - No Aircraft or Airport.
- Facilities must have Pressure Dome (w/ head shield) upgrade.
- Combat units will suffer extreme attrition due to high heat and restrictive atmosphere and heavy pressure outside pressure domes.
