Half-Life:Blue Shift

Half-Life: Blue Shift is the second, stand-alone expansion pack for the first-person shooter computer game Half-Life, developed by Gearbox Software and released on June 12, 2001. Like Gearbox's other expansions, Half-Life: Opposing Force and Half-Life: Decay, Blue Shift returns to the setting and timeline of the original story, but with a different player character: the ubiquitous Black Mesa Research Facility security guard Barney Calhoun. As Barney, the player attempts to escape the alien invasion caused by the resonance cascade and the ensuing military cover-up.

Blue Shift has now been released via Steam and can be purchased individually or in a pack with several other Half-Life titles. A third-party remake of Blue Shift for Source is under development.

The title has a dual reference to the actual blue shift effect, which is the phenomenon of light from stars appearing bluer as they move towards the observer and "Blue Shift" is a way of referring to the facility's security guard's work shift. Various game manuals refer to security shifts in color codes. The events of the game follow Barney as his "Blue Shift" coincides with the Black Mesa Incident.
