I only recently got a PS4, after having gotten very used to using gyroscopic aiming on my PC for games like Tomb Raider (2013). I was completely unable to play Horizon Zero Dawn using only the sticks, so after much searching of Reddit and YouTube (and a fair bit of experimentation) I have figured out how to use it on my PS4 as well, with the help of my PC running steam and other software.
This guide will show you what I do to get it to work. In the process, you will also see how this process can be tweaked to unlock many options for PS4 control, including using the Xbox Elite controller, Nintendo Switch Pro controller, or Steam controller with your ps4.
Note: This technique is not free – it will cost you a minimum of 12 British Pounds (about $14 right now) for the software.
