Once you obtain a level 13 Finca, you can create and save Base Layouts! You can save both building and Sicario placements into a layout. Switch between your layouts to find an optimal defense strategy. Objects built after saving your Base Layout can be placed in areas that are free. Be sure to save your current Base Layout before switching to another, or it will be lost!
To save or switch your Base Layout, just tap the Builder Cabin and then the arrow cross button.
