The 2nd level of the Tunnel was more of a market, the first of many in the Pit. To be more accurate, the two neighborhoods stretching in front and behind the stairs were the market. The area was much more crowded, with narrower walkways due to all the stalls lining the center of the street, as well as the front of each building.
Old parts, broken electronics, scrap metal, containers filled with mystery fluid. Some had entire vehicles dismantled to bare parts and put up for sale, others brought in objects clearly ripped out of their natural place. The weirdest thing Dante saw was a couple of ancient ATMs that had clearly been around for half a century. There were shops and stalls dedicated to clothes and shoes, too.
