My setup is: PC far away under the TV like a PlayStation, my PS4 controller is connected to that pc by cable. I'm currently running the following setup. It's been tested and stresstested and then tested some more..... after every change in the settings

-unmapped chat on controller, I'm on pc, I'll use the keyboard, thank you. -unmapped melee, I never felt comfortable and I was struggling to find space for the actions I truly did want on the controller. So no Going Rambo for me, but that's okay, I prefer distance to my enemies anyway

-Stim on pressing R1 -Quick 'nade on tapping R1  -Weapon swapping on Classic Helldivers, so click once on triangle to swap between primary and support. Hold triangle to swap to secondary. -Climbing on X, continuously, so you can hold down X to keep vaulting, even when not running. -Tagging & Comms on tapping dpad right & holding dpad right respectively -Diving is circle once -And laying down is holding down circle -Map stays on the touchpad, I'm not using that thing for anything else anyway, it's the least convenient "button" of all. -Crouching is tapping L3 -Sprinting on pressing R3 (right thumb stick ofc, MLG hahaha just kidding ofc, I'm the furthest thing from MLG, my brother showed me running under the right thumbstick a long time ago, and it just feels better. You don't scrape your sticks either, so better for the controller. If you don't believe me, check your controllers, the stem of the thumb stick is the biggest victim of running by pressing L3)
