It is not compatible with original PlayStation titles or PlayStation 3 titles. The controller is released in black in Japan, blue in Europe, and orange in North America. 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. Two new smaller buttons, SELECT and START, have been added to the left side of the shaft. 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.
GunCon 2, Japanese domestic model: a d-pad has been added to the rear of the gun Electronic Gaming Monthly 's Crispin Boyer said that a Namco public relations representative was shocked when he informed him that he'd tried the GunCon with Maximum Force (not a Namco game) and confirmed that it worked. 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. Time Crisis 4 came out for the PlayStation 3 bundled with the GunCon 3 NC-109 (G-Con 3 in Europe ).
A second version of the GunCon, known as the GunCon 2 NPC-106 (G-Con 2 in Europe), was bundled with the PlayStation 2 conversion of Time Crisis II and Time Crisis 3. 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. The first GunCon NPC-103 (G-Con 45 in Europe) was bundled with the PlayStation conversion of Time Crisis.
