The PlayStation platform's features continued to evolve and get updated a lot, but the PlayStation 2 controller had buttons that held a big secret that you might not know about.

Most of the DualShock 2's buttons can detect up to 256 levels of pressure, which is a technical feature that opened the door to different solutions and gameplay situations, and the only exceptions were in some buttons like the Start button and the L3 and R3 buttons. Even though not all developers explored this technology in their games, the uses of this technology in some of the most popular titles of the time are fresh in our memories.

In the Gran Turismo car racing series, for example, on the PlayStation 2, it was possible to simulate the level of foot pressure on the accelerator pedal, that is, the harder the X button was pressed, the faster the car would go, and vice versa.

Rockstar Games took Polyphony Digital's game as a vivid example of this simulation with Grand Theft Auto: San Andreas, which offers the ability to adjust the speed of the vehicles driven by CJ. Even cooler is Hideo Kojima's use of it starting with Metal Gear Solid 2 Sons of Liberty, where a light press of the square button can be increased and will make Solid Snake aim the gun without firing, and the button can be pressed even further to shoot.

Old platforms, although they are certainly technically behind current technologies, some of the previous technologies confirm the degree of innovation that some companies have achieved at this time to dazzle gamers, and in fact the PlayStation 2 has achieved this, being the best-selling home platform to date.
