Sony consulted with a select group of PlayStation-owned studios as it was building the DualShock 4 controller for PS4, according to two developers at Guerrilla Games.
In an interview with CVG, Guerrilla game director Steven ter Heide said the new DualShock is "a great controller for an FPS".
"We've been having these discussions about putting a headset jack in there because everybody should be able to go online and have a chat, and they put it in there and it's awesome," he said.
"It sounds like a lot of really simple features that we've put in there but they make all the difference because it's in one comprehensive package. For example, there are little tweaks to the indentation on the sticks, where you have your thumbs on them, we've slightly raised them so there's a little bit more precision. They're slight changes but they make a huge difference."
He added that Sony took on feedback from a number of developers within the Sony Worldwide Studios network. Evolution Studios, for example, offered feedback on the motion control aspects with racing games in mind.
Guerrilla co-founder Hermen Hulst said the DualShock 4 was "a big step forward from what we have [on PS3]"
He went on: "It feels incredibly accurate, in your hands it feels solid, it feels really high quality with the materials that have been used, it feels like you're in control and particularly with that feeling of being a Shadow Marshal, this big hero guy with extra capabilities, it's very suitable.
"And like we said earlier, we've been feeding back on what it should be for so long that I think we have what we wanted to have. It's very suitable for Killzone."
Sony revealed the near-final DualShock 4 controller at its PlayStation Meeting last Wednesday. The impression the company wanted to project is that Sony has built its new hardware with developers in mind.
ter Heide said: "This was the first time we did this with PlayStation, where you get the entire group of core developers together and consistently give very deep, profound feedback on everything system-related, and that's really awesome.
"The guys who made [the system] are no longer in an ivory tower in Tokyo, it's shared with us and not just with us, but with Evolution, Santa Monica, Naughty Dog, everybody and together we've built the machine."
Elsewhere in the interview Guerrilla confirmed that Remote Play would be a standard feature for Killzone Shadow Fall - allowing the game to be streamed onto Vita.
