Half-Life High Definition Content

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