You can attack the Kabamzano Family (NPC) or other players by clicking on the map via the button on the lower right side.
On the map, choose the light green marked neighborhood and the block of the NPCs you’d like to attack. Click on the “Start attack” button to get to the menu of fighting arrangements.
The units of the enemy are on the green positions. Yours are the red ones. On every spot you can position one of your units, choosing the particular type of units first. If you would like to use more than one unit type, make sure to not position all your units on one spot when starting to arrange the fight.
Is your setup ready, click “fight” to start the battle.
