A little shower thought.
When you first start out, you would probably only have enough Heroes and Hero power to make it through the first campaign District flawlessly. Likewise, you would probably only have enough Heroes and Hero power to make it through the first stage of the Gauntlet.
Of course, as you begin to play for months on end, you would soon get more than enough Heroes to complete higher level Districts and Gauntlet stages flawlessly.
What I’m asking for is this: if you fully three star all missions in a District, you unlock a Gauntlet stage corresponding to that District. That, plus I want to see more Gauntlet maps aside from the stage one bank, stage two and three dried aquarium, and stage four and five stock market exchange.
