Half-Life: C.A.G.E.D.

The game begins with the player in a cell with other prisoners inside the Correctional & Automatic Guardhouse Electronic Detention. The player has to get out of the cell and escape by using the pressure of the pipe to blow it up, leading into a sewer. The player then makes their way throughout the facility while evading or killing the guards, climaxing at a battle at the docks of the prison to get to a speedboat.
