Much life Half-Life, the Pak files should be restored. However, I would like to point out an issue in live Blue Shift on Steam.
There's HL data that Blue Shift should actually just call back to the Valve dir for. Blue Shift originally provided a stripped down pak0.pak to compensate for the fact that it was a standalone expansion. When Blue Shift was brought to Steam, all 3 Pak files were extracted, resulting in the content from pak0.pak being provided too despite the fact that Blue Shift also reads from the Valve dir.
If Pak files aren't restored, then the HL content needs to be stripped out of the build.
If Pak files are restored, then pak0.pak and other select files (such as WADs) should be withheld.
## Incorrect Blue Shift icon
This is massive low hanging fruit, but for whatever reason when Blue Shift shipped on Steam in 2005 the icon was entirely redone. While it doesn't matter much to change it on Steam (as all games have differing icons,) the game.ico/tga should either not be provided or should be swapped out with the valid Blue Shift icon.
