H. Mason Maximum Security Correctional Facility is the prison featured in the Dead Pixels campaign The Solution. It is speculated to be somewhere in the state of New York, USA, but the exact location is unknown beyond that it is in the United States.
H. Mason serves as the home for the six criminals who later become heroes in an attempt to save New Hexington from the zombie horde that plagues its streets. These criminals are R. Kirkman, M. Brooks, S. Perry, W. Ellis, S. Smith, and J. Russo. The convicts are briefed by E. Vickers about their mission in the prison, then flown to New Hexington to complete it. There is no return to H. Mason after their flight as they are either going to die or be set free upon accomplishing of the mission.
