an old game nobody can figure out its name?

when i was younger ive had a strategy game, ive no idea what was its name, kind of a combination of tiberian sun and dune/emperor.
it takes place in space in a somewhat of a mountainy place at dark...
it starts with a machine that looks like a half circle and it plays as the harvester.
i believe it has three kinds of armies:
a robot, its buildings were yellow and blackish
an astronaut, his colours were white and purple and i cant remember the third one unfortunately...
i think that if you gain more and more experience it gives you more options of buildings and war machines and stuff
i remember a powerful war machine, it was some kinds of a spaceship with 3 little spaceships inside of it and it sends them to battle.
the game had a pretty good graphics for its time and the command toolbar was down screen.

thanks you!
