Instructions
Brief
You will begin with three cities and three factories. Your objective is to
protect the cities from Missile attacks by knocking them out of the sky with
your rockets. Incoming Missles will leave a red trail and your rockets will
leave a blue trail. When the three cities are destroyed you lose. The three factories
will make the rockets for you, though you can stockpile only a limited number.
If you lose a factory, your production rate will drop. At the end of each
level you will have the option to upgrade some attribute or add a shield to one
of your cities or factories.
