Still don't get why Ubisoft named their upcoming strategy game R.U.S.E.? The newest gameplay trailer explains just what a "ruse" is and why you'll find them useful in a battle.

"Ruses" are special abilities that allow you to either deceive your enemy or gather intel on them. In this video, you use an ability called "decipher" that allows you to see enemy troop movements from afar. Surveying the battlefield is made easy by R.U.S.E.'s IRISZOOM Engine, which allows you to quickly zoom in and out on the action.

R.U.S.E., first revealed at GDC 2009, will be released during the 2009-2010 fiscal year.
