Backstabbing is a good way to inflict some extra damage onto the targets which you must fight to complete the level. It's a simple task. When the character has not initiated a fight with you/you have not initiated a fight with them, stand behind them, so you are facing their back, and hit them regularly. If completed correctly, it should say in comical letters on the screen "BACKSTAB!"
