Its a free turn based RPG. So it says. Its 3.99 to remove the 30 long advertisements. That appear every 15 turns. You have earn exp. to unlock upgrades for your "heroes". Then in order to get said upgrade it cost gold on an increasing slide scale for each lvl. Gold is sparse through out the cookie cutter missions. But you can buy more for the low low price of $9.99. So if you are a pay to play person the healer hero will set you back 19.98. If your not you will stuck buying healing potions at 5 for 1000 gold basically making it impossible to lvl your heroes
