"Matt, while you're looking for a way out, try to find one leading out to a secluded area... maybe sewage access. I'm not so sure the people outside are going to be expecting us with welcoming arms..."That gave you an idea, and following through it proved to be a success. Underground level 2 had a place, far from where one would expect any customers, that led directly to the sewers. It was kind of like a secondary access hatch for maintenance reasons, in case of accidents in engineering levels. You were sure it would be closed but it probably wasn't locked down in the same way as other exits.
You guys know this area at all?
