Observatory

A great way to expand your might is by colonizing new planets! You'll need this building to do that!

— In-game description.

The Observatory is a main building that allows the player to colonize other planets.

Information

The Observatory allows the player to split their progress and resources through different colonies. For each level it gets upgraded, one new planet will be available to be colonized. This building can be built only in the main planet and not in colonies.

At higher levels, it can be an useful defensive building to distract enemies' units due to it's high health points and low loot. It also takes an extremely high amount of time to upgrade it, so it's recommended to get friends' help to accelerate the process. Observatories also require a lot of both coins and minerals to upgrade.
