A sci-fi RTS game with base building and resource gathering.
Colloblast: Kingdoms of Cosmos
SteamColloblast - Kingdoms of Cosmos, is a real time strategy game (RTS)
After the war, surviving nations had to search the stars for uncontaminated water. Civilian colonies were created on planets and asteroids, but the settlers would soon realize that humans aren´t the only species that treasure this valuable resource. Explore new worlds, be wary of what lurks out there, and deal with the past in search of a brighter future.
Classic mechanics
Gather resources, build structures and wage war with multiple factions.

Multiple fronts
Control underground, ground, flying and orbital units.

Detection
There are three layers of visibility: hidden units, detected units, and visible units. Many units will first know that there is something there, before knowing exactly what it is. Some units with "radar" capabilities will have a much greater detection area, but detections can also be faked, or triggered by wild life.

Unit behaviour
Besides resources to build, your units/vehicles require supply, power and morale to function on the battlefield. When this runs low, your units may get a worse aim, some can get afraid and flee, some can freeze and not move, and more. Your units can remember who they were in battle with, which can give a morale boost, but it can have the opposite effect if the worst happens. Fear and trauma can have strong effects. Leaders, supply units and more, will help your units overcome this when they are far from the base.
