I bought a controller for my PS4 for APEX only. I have the basic macro buttons on the back. Set up the right back button to be a turbo trigger. Makes the Hemlock and the G7 deadly and I don't need a select fire for the Prowler anymore. The left back button I programmed to double tap for syringe or shield. Sounds like a little mod but you don't have to take your thumb off the left stick and you can keep moving, then tap the back button once to pop a shield in a gunfight.
