Observatory 3

"A great way to expand your might is by colonizing new planets"
  — in-game description 


  • The Observatory enables you to get multiple Planets/Colonies. The higher level the observatory is, the more colonies you can colonize.
  • On new colonies/planets your Star Base looks different and the background scene might be diferent, for instance snowy(Blue colony), warm(Purple colony), gloomy(Green colony), etc.
  • You can have only one Observatory (in your main planet) ! Colonies can't have observatories.
  • You get 1 new colony per Observatory level up to the maximum limit of 11 new colonies, apart from your main planet. (12 planets total)
  • The Observatory has more health than the Star Base up to level 8, and has very little loot. This makes it excellent for a defense building.
  • Observatories take an extremely long amount of time to upgrade. In fact, the last few upgrades take about a month. Plan ahead before upgrading your Observatory, and remember to get friends' help.
  • The total time to fully upgrade the observatory is about 5 months and 4 days!
  • Observatories, similarly to higher-level star bases, require massive amounts of coins to upgrade.
  • As you colonize more, it will be easier to continue colonizing, as you may have more mines to collect minerals.
  • The appearance will kept the same after level 5 until level 11 (max level) .
