Here are some mappings for Lords of the Fallen that you can use to make your game have the same inputs as Dark Souls did.

I swapped switch weapon and powerup, among other things. [Warning - This only changes your game-pad's mappings]

Here are the mappings that I changed/also some that I didn't [for reference only]:

DPAD RIGHT - Switch magic to be fired out of rocket arm

DPAD LEFT - Activate Special attack/powerup

DPAD UP - Switch selected Special attack/powerup

DPAD DOWN - Switch equipped item

A - Pickup item/activate

B - Roll

X - Use item

Y - Two-hand weapon/shield

//Y - If you equip rocket arm that will be the third thing to be switched to by Y - It's personal preference really

Start - Open inventory

Back - Open options menu
