3D Movement but the player can only move backwards (Beginner)

I want to make a small game where the player can only move backwards (3D First Person) and everywhere I look there’s the Horizontal and Vertical movement systems which I can’t change, and the ones I have changed don’t move, even when I fix the errors. I’m using a Character Controller. Any way to do this?

If you’re using a character controller, can’t you just use controller.Move(-transform.forward);? -transform.forward is the reverse direction of forward, which is backward, so your player will always move backwards. @ImARealPerson (or are you real?!)
