However, you must angle your shots with care. Strike too low and your cannonball sputters out before hitting anything. Without enough force, your cannonballs won’t so much as pierce through enemy fortifications. Later levels add the extra difficulty of having to rescue one of your compatriots. You must take out the enemy soldiers without harming the inconveniently placed hostages.

Take advantage of the few environmental factors at your disposal. Normally, artillery fire bounces off your enemy’s helmets. This can be annoying sometimes, but it can be convenient. Want to take down that other soldier? Use his own comrade’s defenses against him!
