Macduff is introduced as the Thane of Fife who grows suspicious of Macbeth and helps lead an army to overthrow him after Macbeth kills Macduff's family. Developing the character of Macduff provides more scope than Macbeth since he is less developed in the play, and portraying Macduff's roles of leading an army, dueling, and other tasks allows for a more diverse game. Macduff fits the game's themes of good versus evil, revenge, and restoring order as one of the main heroic characters seeking to defeat Macbeth through action.
