There should be a new add-on, or update for this. It is the "Rappel Point." With this brick you will be able to scale down the side of a building, or just slide down the rope to the ground. There should also be a "Glass" brick. With the Glass brick, you would be able to break/breach into (with Rappel Point)/climb over it. This would be very helpful for a build I'm working on. I got this idea from the game "Rainbow Six: Vegas." I would make this, but I don't know how to make add-ons. So if one of you people out there could make this, I would really appreciate it. ^.^
