Modern Warfare 4's New 'Counter-Strike' Mode Officially Announced

Call of Duty: Modern Warfare 4 is taking a page from Counter-Strike with a new multiplayer mode built around one of the classic shooter's defining mechanics: buying your gear with money earned during the match. Called Collateral, the new mode puts an economy system on top of the familiar Search and Destroy formula, creating a version of Call of Duty where every death and purchase could have consequences.
