I've seen a map in the MA that runs the other way (office to sewer/cave)...
Arc 55669 - Tales of the PPD: One Hell of a Deal (video trailer)
Arc 64511 - The Wrecking Ball
Arc 1745 - The Trouble With Trimbles
Arc 302901 - HappyCorpse
I have as well. But I really want to move up in the world, so to speak, in my arc.
The Safeguard "sewer bombs" side mission uses a map that starts in a sewer, moves to a cave, then goes up into an office. However, I haven't see that, nor any Safeguard/Mayhem map, in the MA, unfortunately. >_>

I don't know if I'm remembering things correctly, but I seem to recall a mission on an office map that begins in a sewer or cave and leads into an office space. Is there such a map available in the MA?
