When the Playstation 2computer entertainment system was announced, the Dualshock 2 (SCPH-10010) included with it was almost exactly the same externally as the previous DualShock analog controller. There were however a few minor cosmetic changes. It has different screw positioning and one fewer screw. A blue DualShock 2 logo was added to the top of the controller, the connector is more square than the DualShock, and both the cable and connector are black rather than grey. The standard controller is black (other colors came later), rather than grey as with the original DualShock. The analog sticks are also noticeably stiffer than on the original DualShock.
Internally, the DualShock 2 was lighter and all of the buttons (except for the Analog mode, start, select, L3 and R3 buttons) were readable as analog values (pressure-sensitive).
The DualShock 2 has been made available in various colors: black, satin silver, ceramic white, slate grey, ocean blue, emerald green, crimson red, and candy pink.
The original PlayStation is Forward Compatible with the DualShock 2. The PlayStation 3 is Backwards Compatible with the DualShock 2 by the use of third party peripherals, which connect the controller to the console via a USB port. However, the DualShock 2 will not work properly with games that require Sixaxis functionality, such as Heavy Rain.
