Never heard of it, but if you say it's good, it's worth a look! :D
[EDIT]
From the reviews and images i've seen, i've played this game before (at least the demo)! :o
Just one question: The main resource is some kind of green gas that you have to build a refinery on top of it? Also, you had to build colonies to increase the amount of people for something, perhaps just to build more units...
Are there beacons that can form an energy wall for you?
if so, then i've played a demo of this game before!
I don't remember every detail of it, but i think i played the demo when i still had the original TA:K CD (which was a long time ago)...
Funny thing is, i was trying to remember the name of that game because i wanted to play it (the full version), but couldn't put my finger on it! xD
