Colony structures

From Master of Orion Wiki
Jump to: navigation, search

Colony structures are the basis of an empire, improving various areas of their functioning. All structures are categorized first by the area of a colony's functioning they affect, then by the type of bonus:

  • Worker bonuses apply to each tile occupied by a worker.
  • Flat bonuses apply regardless of worker assignments.
  • Global bonuses apply to the entire output of the planet.
