Twists and Turns

The hardest part about operating in the Metro Area is getting around. Those tunnels twist all over the place, and it's easy to take a wrong turn when you're trying to extract. I've heard there are hidden extraction routes near the restroom and the warehouse. Since you've already spent some time down there, find both of them and make a few more runs so you get used to navigating underground. M.I.C.A.'s compass still works down there, so use it if you lose your bearings.
