Playing Misty Continent, you will find yourself in distant lands in the era of pirates. You have to explore the cursed places, where you will need to fight the ghosts of pirates and build your base to secure it from enemy attacks. To fight the pirates, you need to make your army stronger, which you can do by unlocking new heroes. This can be done by using Hero Badges and Recruitment Banners, but these items, like other resources, will take a long time to farm, so it's a great idea to redeem some Misty Continent codes to get free rewards.
