Shield yourself from enemy ships! These ships are trying to destroy your weapons. Click on “F” to fire at them and “S” to shield yourself from them. If you want to shield yourself from them, you have to solve a math equation! Solve it as quickly as possible, before the bomb hits your weapon. If you have a shield over your weapon, the bomb won’t hurt it. Shoot each enemy ship 5 times to bring it down. Shoot down all the planes while protecting your weapons?
