Sorry if this is old news but this game was just released on Steam yesterday:

I love Arcen games. AI War is great and this one looks awesome. I'm going to buy it next week.

For those who need more information, there's a topic on their forums detailing the game.
Like most indie groups, the developers are quite nice and interactive with the community

And for those that love Strategy games, check AI War!
Also, if you hate Steam, you can buy directly from Arcen Games.

Thanks Starmaker for the above link.

I've mentioned in my post you could get from Arcen so, If you don't mind, I'll edit my post and paste the link you've provided there. ;)
