Faithful L4D1 Boomer Sounds (L4D1 Campaigns Only)

THIS mod but for the default L4D1 campaigns only, except The Sacrifice. No custom campaign support because it is as simple as recompiling the VPK with that campaign's mission file.

You can ignore conflicts with other L4D1 only mods, except for ones that replace the Boomer sounds, in which case you'd need to put this mod over that one.
