Ubisoft has released a demo for R.U.S.E. on Xbox Live.
In it, you get to play a full mission designed exclusively for the demo.
According to the XBL page, you will be able to "command Allied forces from the Head Quarters and lead your army to a nuclear conflict and combine deceptive strategies to conquer the battleground".
R.U.S.E. is out today in the US and on September 10 for PS3, 360 and PC in Europe.
