Dual Shock 2 is similar to Dual Shock, the controller that came with the original PlayStation. This is great news for gamers. The main new feature, is that the controller can measure how much pressure you are exerting when you push the buttons. The controller can now register the amount of pressure being exerted by the user. The Start and Select buttons are the only analog controls. This gives you greater control over the game, allows for a wider range of operations, and makes it more interactive. Two force-feedback solenoid vibration rumblers and two convex, analog thumb pads round out the features. This controller can be used with all software compatible with the Dual Shock original controller. Features 12 keys for added intelligence in your gaming.
