The Soulprint Files
The Lower Tier, also known as the Under Tier or Undercity, is the where the mutants, the cyborgs, the oppressed working class, and the considerable criminal element of Los Santos go to roost. Whenever part of Old Los Santos became overrun with vagabonds, or suffered radioactive fallout, or crumbled into disrepair, the city planners simply built new roads and new foundations over the ruins. This has led to a city-beneath-the-city, a confusing and mazelike warren of streets that connect the city’s power plants, food replication factories, ancient sewage system, and abandoned subway tunnels. Getting from one part of the Lower Tier to another is a confusing process. At times a street will seem to dead end, requiring a traveler to go up to the Middle Tier, then descend again from a street overpass or old subway station to reach their Undercity Destination.
The Grail Free Clinics, run by Grail Biotechnica, are the primary source of healthcare for the denizens of the Lower Tier. Many of the mutants and cyborgs who work in the city’s factories and power plants live in Half-Houses run by the Church of Man. The Venutti Crime Family is in a constant war for territory with the Triad throughout the Lower Tier. Because of the largely underground nature of the Lower Tier, it is difficult to drive a spinner here; most denizens walk, use ground cars or motorbikes, or take a ramshackle trolley that runs along the old subway lines.
