These make up the most of Montrose, and almost all are abandoned, save for a few squatter camps and resistance hideouts. This played host to a plane crash when the EMP blast took out the nation's power grid and the URSA began its invasion. It also is the home of the Montrose Elementary Labor camp. The Oasis is also built into these ruins. The Wall was built by the URSA to keep the population controlled within the city, isolating them and, more importantly, the Resistance. The Wall can be seen from many points within Montrose, including the school grounds. A number of gates are also present and thousands of guards are present to with machine gun on topof the wall. The Wall is the only place in Montrose where there are no Resistance tunnels.
