If you connected your game via Facebook or Game Center you can restore or transfer your progress. 

Should you ever lose your progress for any reason, having connected to Facebook or Game Center will ensure that your game is recoverable in the future. 

Facebook/ Game Center Restore: 
In the event that you need to restore your progress, make sure that once the game is opened again that you reconnect to the same Facebook/ Game Center account that is associated to your Mighty Battles account. You can connect to Facebook or Game Center by following these steps:
  1. Tap the 'Options' (cog) icon on the center of the screen in the main menu. 
  2. Tap on the 'Help' tab.
  3. Tap on the 'Accounts' button.
  4. Tap on the Facebook or Game Center button.
  5. Any Mighty Battles games that you connected to your account with will now be presented in a list. Each game will be time-stamped with date and time it was last accessed, so if you are unsure which game to restore, start with the latest one in the list, and if that is not the right one, simply repeat these steps and select the next game in the list until you find the one you are looking for. 
Please note, if you do not connect to either Facebook or Game Center, you will NOT be able to restore your progress.
All the Best,
Hothead Games
