In 2012, Crowbar Collective has delighted Half-Life fans with release of the magnificent Half-Life remake, but there are still no released remakes for add-ons. This is when they are coming in - HECU Collective are developing the Black Mesa: Blue Shift - a free remake with use of Black Mesa resources and style.
Free fan-made mod for Black Mesa - no budget, no revenue and no commercial release. Built by the volunteer HECU Collective and distributed at no cost via ModDB and the Steam Workshop; the only funding is voluntary Patreon and Discord donations, with no figures disclosed. Note the mod is incomplete: 5 of 8 chapters had shipped as of July 2026, with the remaining three planned to land together as version 1.0.
