Dual Shock 2 is designed to be nearly identical in layout to the Dual Shock controller of 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 creates a more interactive experience. The controller also includes two force-feedback solenoid rattlers, as well as two convex analog rumblers. It's also compatible with software that uses the Dual Shock Controller. Features 12 keys for added intelligence in your gaming. Twin Dual Shock Motors Rumble with Each Action Making Every Impact Feel Like You're Right In The Game
