More precisely send soldiers into battle to the monsters often faced each other, to get as much damage.
At each step you released 10 soldiers.
If the operation is not using all soldiers, will get 10 gold for each unused.
When you do not have enough soldiers for the next mission, then every 100 gold will be used for the hiring of one soldier.
For each level you will be getting stars:
-3 Star-use from 1 to 5 warriors.
-2-Star Used from 6 to 9 soldiers.
-1 Star-used more than 9 soldiers.
Collect as many stars to open new levels.
