http://www.longplays.org Played by: JonL Half-Life: Blue Shift Developer: Gearbox Software Released: Sierra Entertainment 2001 Source port used: Steam version ** Plot As with Gearbox's previous expansion pack Opposing Force, Blue Shift returns to the setting and events of the original game, but portrays the story through the eyes of another person. The protagonist in Blue Shift is a security guard, Barney Calhoun, employed by the Black Mesa Research Facility. After a scientific mishap causes Black Mesa to be invaded by aliens, Calhoun must fight his way to safety. ** Notes The Steam version is the closest to the original that I could find, although the initial menu is different. The game included a High Definition pack that upgraded the models and textures in both Blue Shift and the preceding Half-Life games. This longplay does not use this pack.
