Power

The "Power" is what make you look strong in the game,the more power you have,the more stronger you look,but having a lot of "Power" don't really mean you're stronger than another player.

How to Gain Power
To gain power,you need to upgrade buildings from your city,from your mansion,or the easiest way,recruiting new buttonmen,the more buttonmen you have,the more power you have,of course if they die in a PvP battle you will lose power,but be careful,buttonmen have a hourly salary,so having a giant amount of buttonmen will make you lose money quicker.
