Isaac City Sewers are a winding series of sewer systems that have been constructed to help maintain sanitary conditions for Isaac City. The sewer system is quite large and has a fair number of entrances and exits. There are a few hallways that connect different portions of the sewer system. Towards its far end there is a generator room and warehouse area. This location is a site of conflict when Imminent Storm and other terrorist factions attempt to use it as a headquarters and safe haven. The Isaac City Guard sends in The Raven to destroy them.
