I have been using a DS4 controller to play this game for a long time but my mapping on the ps4 is different. since i have to use the '/gamepad 5" command the controls menu only shows keyboard controls and i am unable to change it to on. is it possible to turn it on or edit the controller mappings by editing a txt or ini file?

See "Gamepad0" and "Gamepad1" in NTT-FAQ document included with the mod.

Okay, I looked at the faq and put

[Controls]
Gamepad0=4

In the NuclearThroneTogether.ini file but what would the names of the commands be? (like what is the text for shoot and special and others?)

Okay, i was able to remap the controller by editing the save instead of the ini file. i had to use the native mac version to make a save file that had my ps4 controller mappings. sorry for the bothering you.
