Mission Briefing:
You're in charge of a high angle artillery cannon. Use the up and
down arrows to adjust the angle of your artillery cannon. There
are 3 enemy strongholds in the area. Use your artillery cannon to
destroy the enemy's ammunition depots.
The enemy ammunition depots are inside fortified valleys and only
a direct hit to the depot can destroy the enemy.
Normally adjusting your angle would require you to do some
calculations, but thanks to technology all of the calculations
are done for you. Just match up your calculated distance to the
reported distance of the targets or use the visual reference.
Up arrow: raise cannon angle
Down arrow: lower cannon angle
Enter: Fire the cannon
