Go to Multiplayer and do 2 versus 2. Have one person on the red and blue team get in Arwings. Have the people from the same team hop on the Arwing's wing. Have the person on the red team hop onto the Arwing with the blue team piloting. You can then shoot each other to hearts content. You will be flying and shooting each other. If you want a different version, get really high. Then destroy the Arwing and everyone will fall. You can then fire at each other. Have fun fighting as pilots in the sky.
