When the IMC instituted martial law in Angel City, massive walls were built and a system of security checkpoints was created to divide the city into many smaller districts. The unfortunate residents of the Harbor District, now unable to move freely throughout the city, are only able to view the glittering skyline from afar. Pilots fighting in the city gravitate to the highly accessible rooftops, using them to cross entire city districts without ever touching the ground.
The IMC's discovery of fuel-rich veins beneath this once-beautiful community led to aggressive, systematic fracking of the area, turning it into a seismically unstable shell of its former opulence. Titans rule much of the jagged terrain, forcing Pilots to move through and take cover within the interiors of the abandoned buildings. The best Pilots will carefully time their Cloak usage for the precise amount of time that is necessary to move between the protective interior spaces, or use every available square inch of vertical surface to string together complex wall-run routes.
