You loved Argentum right? this RTS looks about that calibur, maybe even better, check out the screenshot:
Heres a little info snagged from PPCThoughts:
"There's no such thing as a free meal in the animal kingdom, and in the land of insects, it's every man, or bug, for himself. If you want to survive, you must build a defensible colony. And if you want to thrive, to conquer, to become the BugLord, you need an army, complete with mercenaries, assassins, and the resources to support them. The task of conquering and defending a new home for your colony rests solely on your shoulders. You must assign workers to forage for aphids and pebbles and you'll have to battle other bug colonies that desperately need those same resources. In this world, there's not enough to go around, and if you want to make it, you must be ruthless."
