Alien Kingdom

Alien Kingdom is a first-person city-building and strategy game with medieval and sci-fi settings. You explore, rescue villagers and escort them home to help grow your kingdom, while building its economy and defenses and raising an army. Enemy bases periodically send invaders to attack; defeating their leaders unlocks worlds to travel between and colonize, expanding your empire.

Build your kingdom

Construct utility buildings such as farms, houses and resource buildings, along with defensive gates, towers and walls. Unit buildings recruit and upgrade offensive units. You can alter your kingdom freely, with no limit to the number of villagers you can rescue or buildings you can construct on each planet.

Develop and fight

Leveling up unlocks more advanced structures, weapon types and greater control over the weather. Combat uses multiple abilities, several weapon types and utility functions, as well as different kinds of weather. You can keep expanding your kingdom and army without limit, and order your units to hold, follow or attack a designated area.

Worlds and difficulty

The game has four worlds to explore and conquer, each with its own enemies and atmosphere. You can adjust the overall difficulty and dynamically change the intensity of enemy attacks, raising it for base defense and lowering it to focus on building, adventuring or attacking an enemy base.
