Empyrean Frontier (itch)

Empyrean Frontier is a singleplayer RTS in alpha development featuring massive space fleets, base building, and resource collection along with a procedurally generated campaign where the player takes a persistent fleet of units through a randomly generated galaxy map. Empyrean Frontier is built on a custom game engine by a single developer, and aims to create an innovative strategy game that is still familiar to veterans of the genre.
