In the game 𝘚𝘪𝘦𝘨𝘦𝘳 2 you will have to destroy the fortresses with cannonballs launched at full power on the most vulnerable parts.
Scan each castle and use as little ammo as possible to completely destroy the structures. Be careful, you will sometimes have to leave certain parts of castles intact to save the poor innocents who are being held prisoner. You will be able to exercise your demolition skills in no less than 68 levels!
