Craft of the Gunner

This is the time to brandish your weapon, Steve. Discharge your firearm and initiate your leap. Use your shots to propel yourself and maneuver in any direction you desire. Ready your bow and release the arrow. Your task is to gather all the boxes. Accumulate the boxes and eliminate all the unseen monsters. These creatures will remain hidden until you have collected the boxes. Therefore, prioritize collecting the boxes, then track down the monsters!
