"The R.U.S.E. demo is now available on PC, which you can download on Steam. The demo features a full mission in which you play a role in the Allied offensive in Italy, aimed at cutting off a German offensive from withdrawing by attacking them from behind. However, high command suddenly realizes that the Germans, aided by the remaining loyal Italian units, are much stronger than they had previously been led to believe. You will lead the US army fighting against Germany and Italy, and must combine deceptive strategies and eventually resort to nuclear strikes to achieve victory!

Console players: it’s just a matter of days before the same demo releases on XBOX LIVE and PlayStation Network!

R.U.S.E. launches on PC, XBOX 360 and PS3 on September 7thNA and the 10thUK."
