The PlayStation 2 comes standard with the Dual Shock controller, which has two joysticks, a directional pad, four face buttons and four shoulder buttons. Third-party controllers from companies like Logitech may incorporate extra features that offer advantages in certain games. One of these features is "auto fire," which is also known as turbo mode.
The auto-fire/turbo setting on some third-party controllers allows the buttons to continue their function for several seconds after the user has pressed them. The controller can be programmed to assign any of the face or shoulder buttons to be the auto-fire/turbo button. For example, a user can program the auto-fire button to "Square." The user will then only have to press "Square" once, and it will continue to "press itself" afterwards.
The auto-fire/turbo buttons can be programmed to continue firing in varying intervals. A small slider located on the controller displays various settings, from slow to fast. The button will fire in quicker bursts if the auto-fire duration is set to "fast" and longer intervals if it is set to "slow." The time between automatic button presses will vary by the controller.
An auto-fire/turbo button gives players many advantages during games. It allows users to perform more complex maneuvers more easily. For example, during a shooting game, using the auto-fire function will free up fingers for simultaneous movement or jumping. It also makes button-mashing games that depend on rapidly pressing a single button (such as "God of War") much easier.
Using auto-fire buttons is often considered to be cheating in video games, particularly in multiplayer games where players compete against each other. Auto-fire controllers are typically used for first-person shooting games, since they can help users fire weapons faster than a human could in reality. As such, they are basically a form of cheating. They do make auto-fire/turbo controllers for the PlayStation 3, the successor to the PlayStation 2, and there is no indication that Sony bans the use of these controllers in online competitive games, despite the unfair advantages they bring.
