1) How do you build multiple floor levels going up and down, do I need to build everything in a single map or can I load between multiple maps ?
2) How do I expand map size without starting a new one ? I started on a small map size and I realized that I need more space. I will also need this for question number 1 if I had to build more on the current map to have floor levels
3) How do I trigger Turrets to spawn when a button is pressed ? Because they already spawn and when the button is pressed they get destroyed and respawn again
