Prob one of the best pc games I have ever played. Definitely in the top 5...
It is a war game with a birds eye view of the battlefield and you command various units such as tanks, artillery, helos...Very strategic and it has qute the online following for being brand new.
The game scales nicely to lesser machines, 2.0 ghz/512 ram/6600 GT being the minimum specs. Those of us who have dx10 cards are in for a treat! It has all kinds of eye candy just for us. Good thing is it can also drop back to dx9 too..Multiplayer is a blast.
