Sony put the future of the DualShock 4 in the hands of developers, who dictated changes to the longstanding controller's form and feel. Guerrilla Games (Killzone ) and Evolution Studios (DriveClub ), in an interview with Edge , discussed the pivotal role they played in encouraging Sony to make changes.
Prior to consultation, the DualShock 4 had outwardly curved triggers, the thumbsticks weren't indented, and it relied on accelerometers instead of high-frequency gyros (mmm, delicious). None of these are jaw-dropping changes, but they all contribute to a controller that feels right. As even a great-looking controller can make for a miserable experience if it gets in the way of gaming.
"[Early DualShock 4 prototypes] looked like something that Bruce Wayne would carry," Evolution's technical director Scott Kirkland said, in an Edge interview. "It was very industrial in design, plastic, [and] there were things that would come off. I remember seeing paperwork for the import and export prototype, and you know all of them were handmade and insanely expensive and we felt privileged to be getting these samples."
