Keyboard Control: Moving Backwards

I am creating a type of FPS that has keyboard control. I have figured out turning and moving forward. The hardest part.. is moving backwards. I have got it to work, but he turns around to move backwards. I was wondering if there was a way to have him move backwards and force him to face the same direction while moving.

Thanks!

If it's single player, then the player would never see his own unit and you ignore the fact that the unit is going backwards, but force the triggers to stop the camera from turning around for that time. If it's multiplayer.... the person moving backwards will be looking one way and facing another.
