Aliens seized the earth and your mission is to clean the mess up. your goal in each level is to use the powerful cannon to destroy the alien. at the same time the spaceman must stay alive. use your mouse to aim the cannon and click and hold left mouse button to build the power of your shoot. release the button to fire. there are several surrounding objects (magnets, ice spikes etc.) that will affect the trajectory of your shoots. good luck captain!
