The gun uses a USB connection as opposed to a PlayStation controller port of the GunCon 1 and also hooks into the video signal of the console either composite video or the Y signal of component video. These new buttons served to open new gameplay opportunities, such as character movement in Dino Stalker or the ability to use two guns at once in Time Crisis II. Prominent additions to this second GunCon model is a D-pad at the back of the gun barrel and a C button added at the bottom of the gun handle. The side buttons, A and B, have been moved rearward to a position directly above the trigger. GunCon 2 G-Con 2 in Europe features a smaller body, as well as a more rounded shape when compared with the original GunCon. Many games that support it allow the A and B buttons to be swapped, making it comfortable for both right and left-handed players. The controller is compatible with some PlayStation 2 GunCon titles, but is not compatible with PlayStation 3 due to its lack of controller ports. The controller is released in black in Japan, and gray and eventually, in orange in both Europe and North America.
It features a button below the barrel on either side of the gun buttons A and B, both performing the same function for auxiliary in-game control, such as to take cover and reload in Time Crisis. The GunCon controller known as G-Con 45 in Europe uses the cathode ray timing method to determine where the barrel is aimed at on the screen when the trigger is pulled. This was because Namco designed the GunCon so that it would only work with Namco games. With the exception of the North American localization of Elemental Gearbolt and Maximum Force games that support the Justifier are not compatible with the GunCon and vice versa. Prior to the GunCon, the Konami Justifier was the first light gun peripheral for the PlayStation and a few games support it. In Japan, all three GunCon models were also available for sale as a separate accessory outside of a game bundle. To make the gun affordable to consumers, the force feedback feature of the Time Crisis arcade gun was omitted, and an additional fire button was included in lieu of releasing a pedal controller for the game's ducking mechanic.
