PlayStation's lead system architect has revealed that first person shooter developers had a say in the design of the console's controller, the DualShock 4.
"We sent out prototypes to major FPS creators," Mark Cerny told IGN.
"We looked at the top-selling titles, if they were people we could talk to, we began sending over a stream of controllers. And we would ask them things like concavity or convexity, or trigger pressure, or trigger location, or accuracy, or the like."
He called the input "extremely helpful."
The DualShock 4 features a new touch pad, new colour LEDs, a Share button, a built in speaker and new ergonomic shape, but has held onto its parallel joysticks.
"We made and tested a ridiculously broad style of controllers and we would actually have people play games with them. And the current controller design came out of that. We did indeed conclude that the two joysticks on the same level works perfectly well. That did come out of our testing."
