The level begins with Proxy inside a Civil Security base. It is unknown why is she there, however, Civil Security calls her to be stopped. Proxy has to make her way over to a Shotgun CS-DAZ and evade enemy bullets. When the shotgun is equipped, Proxy kills all of the enemies in the initial section of the map, going back to the start point to kill the Boss who called for her demise. A switch is activated that enables a lift to bring Proxy up to the second level of the base. Here Proxy neutralizes more enemies, particularly Civil Security Lites, and finds a crate containing a Heavy Railgun v04 CS-OneSOneK. The player proceeds through the remaining area of the base and completes the level by getting on a moving platform going up to the next level.
