As of until now there's been no 3rd party PS4 controllers on the market. But that's about to change with Horipad 4 FPS!
Made by Japanese Perhipherals company Hori, the Hori FPS is first and only 3rd party controller compatible with the PS4 (in all regions) on the market right now, it is available in Japan at present - BUT you can import it right now through Play Asia here:
Honestly reminds me of the layout of a Xbox controller just with the PS buttons, I like the look of the PS4 controller, even though I haven't used it but I see that this is great for those who want a cheaper second controller.
I would get this if I had a PS4. And if it had the light bar, look i know that heaps of people hate the light bar but its there for a reason. Its for morpheus, which for those who don't know is a VR headset. They didn't tell us this before at launch because morpheus was still meant to be a secret.
