This maps 99% of SS1's controls to the DS4, with useful design features. For example, clicking the pad opens the map, and using circle opens inventory. I based this design on Arkane's "Prey", since that was a really seamless experience for me on PS4. Please note: touching the right-side of the pad disables / enables the mouse, which is an unfortunate artifact of the time when this game was released. Holding/releasing the left trigger will briefly allow you to use the mouse with right trigger for click. Both bumpers, down on the d-pad, square, and circle can be tapped or held for alternative in-game actions. I used the left side of the pad to cram in extraneous controls. There are more features which you can discover yourself. Enjoy!
