HeySeuss is going to help me out and handle the opener.
A few things (and HeySeuss can correct me if I'm wrong on anything):
The opener will start DURING a set-up run.
It'll involve a bit of combat. Nothing too heavy.
The group will already be assembled, doing a run to get their hands on heavy equipment that would be impossible to trace. (Otherwise they could just buy it/have a fixer provide it.)
