The Metro Tunnels are vast routes that spread all throughout the Old World, and will be a featured location in the Scarf Heroes Anime. A large amount of pathways are blocked off by rubble or barricades made by uncivilized people. There are little to no signs of radiation as all entrances have been obstructed. Some forts are actually maintained by decent folk as well. Mercenaries tend to not ask questions and shoot on sight.
All Metro Tunnels fluctuate mainly in the Old City, but also stretch beyond Crestfall underground. There is a very large Zombie population within these routes, however some infestations are known to be trapped from ceiling collapses and barricades. The Mercenaries residing at the Stripe Club have almost entirely mapped out the majority of the Metro Tunnels due to their knowledge in finding alternatives to reach the Old City other than the Highway. There are societies and forts built within these tunnels by uncivilized people because of the low radiation and threat levels. Hellspawn enjoy entering the Metro Tunnels as they tend to regroup in dark areas due to the perfect conditions.
Threat levels are still very high because of the structural instability and uncivilized people.
Zombie groans and growls can mostly be heard while traversing through these tunnels.
Mercenaries try to create safe pathways to convince Sheepy to venture with them.
