The castle is being invaded by giant mutant ants and there seems nobody that got the courage to stand up and fight the giant ants. Fortunately that Hawkeye was within the vicinity and decided to defend the castle from the invading ants. Some of the ants are carrying special power, which you can use when you kill them. As you progress in the game, you will be unlocking more powerful arrows that you can use to fight the invading giant ants. The game is played with the keyboard and you don’t have to repeat clicking the keys to fire. Just hold down the key and Hawkeye will keep firing.
