Alien Assault is a powerful arcade game filled with action as this time you will play as an alien that must destroy the town in order to clear it for a landing strip, but this will not be too easy. There are cannons mounted on the ground and they will shoot at you until you also destroy them.
The city that you have to destroy is pretty big so it might take a while to destroy it, but you should take care of the cannons first as you would not enjoy to get destroyed in mid air and you would make a fool of yourself.
