Barney Calhoun


 * In the playable Half-Life 2 Beta files can be found the model of a slightly damaged security guard helmet, named "BarneyHelmet". Appearing as a Metrocop helmet separated into two parts in the retail files and used upon first meeting Barney in the City 17 Trainstation, it was either used as a place-holder early in development or suggests Barney was to have kept his old helmet, as it appears rather worn out, and it would have been seen at some point during the game as an Easter egg. It is also seen in the Half-Life: 2 beta map dsp_test.
