Half-Life: Blue Shift is a standalone expansion for the original Half-Life, developed by Gearbox Software and released on June 12, 2001. It revisits the Black Mesa incident from a different viewpoint, letting players experience familiar events through the eyes of a facility security officer rather than the scientist protagonist.

The expansion focuses on the chaos inside the research complex, showing the incident’s impact on staff and security personnel and expanding the series’ timeline from a fresh angle.

The experience leans into action and exploration, offering new sequences that complement the main game’s storyline.

Release history and accessibility

Originally launched in mid-2001 by Gearbox, Blue Shift was later distributed through Steam, making it accessible to both newcomers and longtime fans who want to revisit this chapter of the Half-Life universe.
