Half-Life High Definition Content

This addon is available for download.
You can either install this addon or remove it.

The Half-Life High Definition Content was the content included with the Blue Shift installation of Half-Life (which allowed for various custom content packs, such as ones made by users). With the release of Blue Shift on Steam, the content was added as an on-demand update (although it was never mentioned).

Note:Nothing will happen after you follow the installation link until you run one of the Half-Life 1 series games.
