Welcome to Alien Invasion. First, press the green flag and press "A" key. Use the left and right keys to stear and the spacebar to use the machine gun. The up arrow shoots electricity and the down arrow heals you. Shoot the aliens （lady bugs）to gain points but they launch bombs to dammage you. When you get 100 points A bat which is the boss will appear. The boss will launch nukes which you need to avoid or it wil destroy your force feild and hurt you. When you defeat the boss the game will end. Good luck!
