I'm supporting this, but I have one thing to add:
One of these steps might fail and get you wanted so it would be more fair to each side.
So it will be like 75 percent chance to success the robbery/step, and 25 percent to fail.
+1 cool stuff anaas!
Just a question. Where exactly do you end up when you use the vent? On the roof of the bank? And from there we use ziplines again?
